Secure user authentication scheme with novel server mutual verification for multiserver environments
The fast growth of mobile services and devices has made the conventional single‐server architecture ineffective from the point of its functional requirements. To extend the scalability and availability of mobile services to various applications, it is required to deploy multiserver architecture. In 2016, Moon et al insisted that Lu et al's scheme is weak to insiders and impersonation attack, then they proposed a biometric‐based scheme for authentication and key agreement of users in multiserver environments. Unfortunately, we analyze Moon et al's scheme and demonstrate that their scheme does not withstand various attacks from a malicious registered server. We propose a user authentication scheme with server mutual verification to overcome these security drawbacks. The proposed scheme withstands an attack from malicious insiders in multiserver environments. We use a threshold cryptography to strengthen the process of server authorization and to provide better security functionalities. We then prove the authentication and session key of the proposed scheme using Burrows‐Abadi‐Needham (BAN) logic and show that our proposed scheme is secure against various attacks. 相似文献

In this paper, we cryptanalyze Rhee et al.'s ‘Remote user authentication scheme without using smart cards’, and prove that their scheme is not completely secure against user impersonation attack. The security flaw is caused by mathematical homomorphism of the registration information. In addition, their scheme lacks key agreement procedures for generating the session key to encrypt the communication messages after mutual authentication. Furthermore, a modification is proposed to improve the security, practicability and robustness of such scheme. Firstly, we introduce elliptic curve cryptosystem to enhance the security. Secondly, in order to improve the practicability, our improvement is much more easily implemented using portable devices in global mobility networks; moreover, a synchronized clock system, traditional password table or ancillary equipment are not required in our improvement. Finally, the proposed scheme not only achieves mutual authentication, but also provides the procedure for key agreement and update of secrets for users and servers to increase the robustness.

In 2009, Lee et al. (Ann Telecommun 64:735–744, 2009) proposed a new authenticated group key agreement protocol for imbalanced wireless networks. Their protocol based on bilinear pairing was proven the security under computational Diffie–Hellman assumption. It remedies the security weakness of Tseng’s nonauthenticated protocol that cannot ensure the validity of the transmitted messages. In this paper, the authors will show that Lee et al.’s authenticated protocol also is insecure. An adversary can impersonate any mobile users to cheat the powerful node. Furthermore, the authors propose an improvement of Lee et al.’s protocol and prove its security in the Manulis et al.’s model. The new protocol can provide mutual authentication and resist ephemeral key compromise attack via binding user’s static private key and ephemeral key. 相似文献

With the continue evaluation of mobile devices in terms of the capabilities and services, security concerns increase dramatically. To provide secured communication in mobile client–server environment, many user authentication protocols from pairings have been proposed. In 2009, Goriparthi et al. proposed a new user authentication scheme for mobile client–server environment. In 2010, Wu et al. demonstrated that Goriparthi et al.’s protocol fails to provide mutual authentication and key agreement between the client and the server. To improve security, Wu et al. proposed an improved protocol and demonstrated that their protocol is provably secure in random oracle model. Based on Wu et al.’s work, Yoon et al. proposed another scheme to improve performance. However, their scheme just reduces one hash function operation at the both of client side and the server side. In this paper, we present a new user authentication and key agreement protocol using bilinear pairings for mobile client–server environment. Performance analysis shows that our protocol has better performance than Wu et al.’s protocol and Yoon et al.’s protocol. Then our protocol is more suited for mobile client–server environment. Security analysis is also given to demonstrate that our proposed protocol is provably secure against previous attacks. 相似文献

The mobile cloud computing (MCC) has enriched the quality of services that the clients access from remote cloud‐based servers. The growth in the number of wireless users for MCC has further augmented the requirement for a robust and efficient authenticated key agreement mechanism. Formerly, the users would access cloud services from various cloud‐based service providers and authenticate one another only after communicating with the trusted third party (TTP). This requirement for the clients to access the TTP during each mutual authentication session, in earlier schemes, contributes to the redundant latency overheads for the protocol. Recently, Tsai et al have presented a bilinear pairing based multi‐server authentication (MSA) protocol, to bypass the TTP, at least during mutual authentication. The scheme construction works fine, as far as the elimination of TTP involvement for authentication has been concerned. However, Tsai et al scheme has been found vulnerable to server spoofing attack and desynchronization attack, and lacks smart card‐based user verification, which renders the protocol inapt for practical implementation in different access networks. Hence, we have proposed an improved model designed with bilinear pairing operations, countering the identified threats as posed to Tsai scheme. Additionally, the proposed scheme is backed up by performance evaluation and formal security analysis. 相似文献

The e‐commerce has got great development in the past decades and brings great convenience to people. Users can obtain all kinds of services through e‐commerce platform with mobile device from anywhere and at anytime. To make it work well, e‐commerce platform must be secure and provide privacy preserving. To achieve this goal, Islam et al. proposed a dynamic identity‐based remote user mutual authentication scheme with smart card using Elliptic Curve Cryptography(ECC). Islam et al claimed that the security of their scheme was good enough to resist various attacks. However, we demonstrate that their scheme is vulnerable to insider attack and suffers from off‐line password guessing attack if smart card is compromised. To overcome the deficiencies, we present an improved scheme over Islam's scheme. The security proof and analysis shows that our scheme can also provide user anonymity and mutual authentication, and the security is enough to against relay attack, impersonation attack, and other common secure attackers. The performance analysis shows that the proposed scheme is more efficient than Islam et al's scheme. 相似文献

Nowadays, the password-based remote user authentication mechanism using smart card is one of the simplest and convenient authentication ways to ensure secure communications over the public network environments. Recently, Liu et al. proposed an efficient and secure smart card based password authentication scheme. However, we find that Liu et al.’s scheme is vulnerable to the off-line password guessing attack and user impersonation attack. Furthermore, it also cannot provide user anonymity. In this paper, we cryptanalyze Liu et al.’s scheme and propose a security enhanced user authentication scheme to overcome the aforementioned problems. Especially, in order to preserve the user anonymity and prevent the guessing attack, we use the dynamic identity technique. The analysis shows that the proposed scheme is more secure and efficient than other related authentication schemes. 相似文献

To ensure secure communication in satellite communication systems, recently, Zhang et al presented an authentication with key agreement scheme and claimed that their scheme satisfies various security requirements. However, this paper demonstrates that Zhang et al's scheme is insecure against the stolen‐verifier attack and the denial of service attack. Furthermore, to authenticate a user, Zhang et al's scheme requires large computational load to exhaustively retrieve the user's identity and password from the account database according to a temporary identity and then update the temporary identity in the database. To overcome the weaknesses existing in Zhang et al's scheme, we proposed an enhanced authentication with key agreement scheme for satellite communication systems. The analyses of our proposed scheme show that the proposed scheme possesses perfect security properties and eliminates the weaknesses of Zhang et al's scheme well. Therefore, from the authors' viewpoints, the proposed scheme is more suitable for the authentication scheme of mobile satellite communication systems. 相似文献

In global mobility networks, anonymous user authentication is an essential task for enabling roaming service. In a recent paper, Jiang et al. proposed a smart card based anonymous user authentication scheme for roaming service in global mobility networks. This scheme can protect user privacy and is believed to have many abilities to resist a range of network attacks, even if the secret information stored in the smart card is compromised. In this paper, we analyze the security of Jiang et al.’s scheme, and show that the scheme is in fact insecure against the stolen-verifier attack and replay attack. Then, we also propose a new smart card based anonymous user authentication scheme for roaming service. Compared with the existing schemes, our protocol uses a different user authentication mechanism, which does not require the home agent to share a static secret key with the foreign agent, and hence, it is more practical and realistic. We show that our proposed scheme can provide stronger security than previous protocols. 相似文献

In remote system security, 2‐factor authentication is one of the security approaches and provides fundamental protection to the system. Recently, numerous 2‐factor authentication schemes are proposed. In 2014, Troung et al proposed an enhanced dynamic authentication scheme using smart card mainly to provide anonymity, secure mutual authentication, and session key security. By the analysis of Troung et al's scheme, we observed that Troung et al' s scheme does not provide user anonymity, perfect forward secrecy, server's secret key security and does not allow the user to choose his/her password. We also identified that Troung et al's scheme is vulnerable to replay attack. To fix these security weaknesses, a robust authentication scheme is proposed and analyzed using the formal verification tool for measuring the robustness. From the observation of computational efficiency of the proposed scheme, we conclude that the scheme is more secure and easy to implement practically. 相似文献

Authentication protocols with anonymity have gained much popularity recently which allows users to access any public network without compromising their identity. Several key exchange protocols have been proposed in the literature using either public key infrastructure or identity-based cryptosystem. However, the former suffers from heavy computation cost and latter fails to prevent key escrow problem. Recently, Islam et al. have proposed a self-certified authenticated key agreement protocol based on ECC which removes the above limitations. However, through careful analysis, we found that their scheme lack anonymity and vulnerable to trace the attack, clogging attack, and fails to prevent the replay attack. To overcome these weaknesses, we propose an anonymous self-certified authenticated key exchange protocol by including the required security features. The scheme is formally proved using Automated Validation of Internet Security protocols and Applications software. Also, the formal authentication proofs using Burrows–Abadi–Needham logic ensures successful authentication. Furthermore, the performance analysis demonstrates that the proposed scheme accomplishes less computational cost and is applicable to a client–server architecture. 相似文献

Global mobility network (GLOMONET) provides global roaming service to ensure ubiquitous connectivity for users traveling from one network to another. It is very crucial not only to authenticate roaming users, but to protect the privacy of users. However, due to the broadcast nature of wireless channel and resource limitations of terminals, providing efficient user authentication with privacy preservation is challenging. Recently, He et al. proposed a secure and lightweight user authentication scheme with anonymity for roaming service in GLOMONETs. However, in this paper, we identify that the scheme fails to achieve strong two-factor security, and suffers from domino effect, privileged insider attack and no password change option, etc. Then we propose an enhanced authentication scheme with privacy preservation based on quadratic residue assumption. Our improved scheme enhances security strength of He et al.’s protocol while inheriting its merits of low communication and computation cost. Specifically, our enhanced scheme achieves two-factor security and user untraceability. 相似文献

With the broad implementations of the electronic business and government applications,robust system security and strong privacy protection have become essential requirements for remote user authentication schemes.Recently,Chen et al.pointed out that Wang et al.’s scheme is vulnerable to the user impersonation attack and parallel session attack,and proposed an enhanced version to overcome the identified security flaws.In this paper,however,we show that Chen et al.’s scheme still cannot achieve the claimed security goals and report its following problems:(1) It suffers from the offline password guessing attack,key compromise impersonation attack and known key attack;(2) It fails to provide forward secrecy;(3) It is not easily repairable.As our main contribution,a robust dynamic ID-based scheme based on non-tamper resistance assumption of the smart cards is presented to cope with the aforementioned defects,while preserving the merits of different related schemes.The analysis demonstrates that our scheme meets all the proposed criteria and eliminates several grave security threats that are difficult to be tackled at the same time in previous scholarship. 相似文献

Internet of Things (IoT) is a newly emerged paradigm where multiple embedded devices, known as things, are connected via the Internet to collect, share, and analyze data from the environment. In order to overcome the limited storage and processing capacity constraint of IoT devices, it is now possible to integrate them with cloud servers as large resource pools. Such integration, though bringing applicability of IoT in many domains, raises concerns regarding the authentication of these devices while establishing secure communications to cloud servers. Recently, Kumari et al proposed an authentication scheme based on elliptic curve cryptography (ECC) for IoT and cloud servers and claimed that it satisfies all security requirements and is secure against various attacks. In this paper, we first prove that the scheme of Kumari et al is susceptible to various attacks, including the replay attack and stolen-verifier attack. We then propose a lightweight authentication protocol for secure communication of IoT embedded devices and cloud servers. The proposed scheme is proved to provide essential security requirements such as mutual authentication, device anonymity, and perfect forward secrecy and is robust against security attacks. We also formally verify the security of the proposed protocol using BAN logic and also the Scyther tool. We also evaluate the computation and communication costs of the proposed scheme and demonstrate that the proposed scheme incurs minimum computation and communication overhead, compared to related schemes, making it suitable for IoT environments with low processing and storage capacity. 相似文献

Smart‐card‐based remote user password authentication schemes are commonly used for providing authorized users a secure method for remotely accessing resources over insecure networks. In 2009, Xu et al. proposed a smart‐card‐based password authentication scheme. They claimed their scheme can withstand attacks when the information stored on the smart card is disclosed. Recently, Sood et al. and Song discovered that the smart‐card‐based password authentication scheme of Xu et al. is vulnerable to impersonation and internal attacks. They then proposed their respective improved schemes. However, we found that there are still flaws in their schemes: the scheme of Sood et al. does not achieve mutual authentication and the secret key in the login phase of Song's scheme is permanent and thus vulnerable to stolen‐smart‐card and off‐line guessing attacks. In this paper, we will propose an improved and efficient smart‐card‐based password authentication and key agreement scheme. According to our analysis, the proposed scheme not only maintains the original secret requirement but also achieves mutual authentication and withstands the stolen‐smart‐card attack.

Recently, Li et al have developed a smartcard‐based remote user authentication scheme in multiserver environment. They have claimed that their scheme is secured against some possible cryptographic attacks. However, we have analyzed that the scheme of Li et al cannot preserve all the proclaimed security goals, which are given as follows: (1) It is not withstanding password‐guessing, user impersonation, insider, and smartcard theft attacks, and (2) it fails to facilitate user anonymity property. To remedy these above‐mentioned security flaws, we have proposed an efficient three factor–based authentication scheme in a multiserver environment using elliptic curve cryptography. The Burrows‐Abadi‐Needham logic is used to confirm the security validation of our scheme, which ensures that it provides mutual‐authentication and session‐key agreement securely. Then, the random oracle model is also considered to analyze the proposed scheme, and it shows that the backbone parameters, ie, identity, password, biometrics, and the session key, are secure from an adversary. Further, the informal security analysis confirms that the suggested scheme can withstand against some possible mentioned attacks. Later, the Automated Validation of Internet Security Protocols and Applications tool is incorporated to ensure its security against passive and active attacks. Finally, the performance comparison of the scheme is furnished to confirm its enhanced security with other relevant schemes. 相似文献

In modern, wireless sensor networks (WSNs) stand for the next evolutionary and innovative development step in utilities, industrial, building, home, shipboard, and transportation systems automation. The feature of WSNs is easy to deploy and has wide range of applications. Therefore, in distributed and unattended locations, WSNs are deployed to allow a legitimated user to login to the network and access data. Consequently, the authentication between users and sensor nodes has become one of the important security issues. In 2009, M. L. Das proposed a two-factor authentication for WSNs. Based on one-way hash function and exclusive-OR operation, the scheme is well-suited for resource constrained environments. Later, Khan and Algahathbar pointed out the flaws and vulnerabilities of Das’s scheme and proposed an alternative scheme. However, Vaidya et al. found that both Das’s and Khan–Algahathbar’s schemes are vulnerable to various attacks including stolen smart card attacks. Further, Vaidya et al. proposed an improved two-factor user authentication to overcome the security weakness of both schemes. In this paper, we show that Vaidya et al.’s scheme still exposes to a malicious insider attack that seriously threatens the security of WSNs. Furthermore, we propose an improve scheme that mends those vulnerabilities. 相似文献
