Martínezet al. have proposed a secure RFID protocol recently which relies exclusively on the use of Elliptic Curve Cryptography (ECC) combined with a zero knowledge based authentication scheme. In this paper, we show that this proposed protocol is not secure against the tracking attack. To make the attack successful, the adversary needs to execute three phases. Firstly, the attacker just eavesdrops on the messages exchanged between Reader and Tag. Secondly, the attacker impersonates the Reader to replay the message which is obtained from the first phase. Finally, the adversary acts as a man in the middle to tamper the messages exchanged between Reader and Tag. Then we propose an enhancement and prove that the revision is secure against the tracking attack while keeping other security properties. 相似文献

In order to secure communications between two clients with a trusted server's help in public network environments, a three‐party authenticated key exchange (3PAKE) protocol is used to provide the transaction confidentiality and the efficiency. In 2009, Huang proposed a simple three‐party password‐based authenticated key exchange (HS‐3PAKE) protocol without any server's public key. By analysis, Huang claimed that the proposed HS‐3PAKE protocol is not only secure against various attacks, but also more efficient than previously proposed 3PAKE protocols. However, this paper demonstrates that HS‐3PAKE protocol is vulnerable to undetectable online password guessing attacks and off‐line password guessing attacks by any other user.

To solve the issue of networking authentication among GEO and LEO satellites in double-layer satellite network,a secure and efficient authenticated key agreement scheme was proposed.Based on symmetric encryption,the proposed scheme can achieve trust establishment and secure communication between satellites without the trusted third party.Meanwhile,considering characteristics of highly unified clock and predictable satellite trajectory in satellite networks,a pre-calculation method was designed,which can effectively improve the authentication efficiency of satellite networking.Moreover,formal proof and security analysis demonstrate that the scheme can satisfy various security requirements during satellite networking.Performance analysis and simulation results show that the scheme has low computation and communication overhead,which can achieve the authentication of satellite networking in resource-limited scenarios. 相似文献

In the past decades, the demand for remote mutual authentication and key agreement (MAKA) scheme with privacy preserving grows rapidly with the rise of the right to privacy and the development of wireless networks and Internet of Things (IoT). Numerous remote MAKA schemes are proposed for various purposes, and they have different properties. In this paper, we survey 49 three‐factor–based remote MAKA schemes with privacy preserving from 2013 to 2019. None of them can simultaneously achieve security, suitability for multiserver environments, user anonymity, user untraceability, table free, public key management free, and independent authentication. Therefore, we propose an efficient three‐factor MAKA scheme, which achieves all the properties. We propose a security model of a three‐factor–based MAKA scheme with user anonymity for multiserver environments and formally prove that our scheme is secure under the elliptic curve computational Diffie‐Hellman problem assumption, decisional bilinear Diffie‐Hellman problem assumption, and hash function assumption. We compare the proposed scheme to relevant schemes to show our contribution and also show that our scheme is sufficiently efficient for low‐power portable mobile devices. 相似文献

The mobile satellite communication (MSC) system is a vital communication method in which mobile users and network control centers connect via satellites. Since the satellite's communication is wireless, communication security is a critical factor to ensure accountable communication. Key exchange and authentication (KEA) mechanism is widely used to achieve data security for data transmitted in an insecure or open channel. Different authentication systems are suggested in the last many years to establish safe communication, whereas most existing security protocols are based on factorization or discrete logarithm. However, these systems are no longer reliable by Shor's algorithm as any discrete logarithm and factorization can be resolved in polynomial time on quantum computers. Thus, developing a quantum secure KEA protocol for MSC systems is necessary. In this direction, recently a ring learning with an error-based KEA technique is proposed to ensure a quantum-safe environment. This scheme is quantum-safe and satisfies desirable security attributes but has low efficiency in computation and communication. Moreover, establishing a secure session requires six communications among involved entities. As a result, replay attack detection at an early stage is not possible for the central authority (server), which could delay the server response, and the adversary gets the advantage of drawing a denial of service scenario for authorized entities. We propose a lattice-based KEA protocol for the MSC system to improve computation, communication efficiency, and early-stage replay attack detection. The security analysis of the proposed scheme is presented in the random oracle model. Calculation of performance is also presented to observe advantages in computation and communication overhead. 相似文献

Recently, Lee et al. proposed a simple and efficient authentication scheme for mobile satellite communication systems. However, we find that their scheme is vulnerable to the smart card loss attack, the denial of service attack and the replay attack. To overcome the weaknesses of Lee et al.'s scheme, we proposed an authentication scheme for mobile satellite communication systems to improve security. The proposed scheme possesses the essential properties and security requirements, which should be considered for the authentication scheme of mobile satellite communication systems.

Recently, Chang et al. proposed an authentication and key agreement protocol for satellite communications, and they claimed that their scheme could withstand various attacks. However, in this paper, we will show that their scheme is vulnerable to the denial of service attack and the impersonation attack. Moreover, we also point out that the adversary could compute the session key through the intercepted message. The analysis shows the scheme of Chang et al. is not secure for practical applications.

In this article, the authors shall propose a simple and efficient authentication scheme for mobile satellite communication systems. The proposed scheme can achieve the following security requirements: (S1) withstand impersonation attacks; (S2) withstand denial server attacks; (S3) withstand smart card loss attacks; (S4) withstand replay attacks; and (S5) withstand stolen‐verifier attacks, and achieve the following functionality requirements: (F1) freely choose identity; (F2) provide mutual authentication; (F3) provide session key agreement; (F4) provide user anonymity; and (F5) provide perfect forward secrecy. In additional, the proposed scheme does not use the high complex computation, such as public key cryptosystem or secret key cryptosystem, for the mobile users' side. The proposed scheme is only based on hash functions and exclusive‐OR operations. Compared with other schemes, the proposed scheme has a lower computation cost. It is more simple and efficient scheme.

Recently, Liu et al came up with an authentication with key agreement scheme for securing communication over the low‐earth‐orbit satellite communication systems. However, this paper demonstrates that this scheme cannot provide perfect forward secrecy or defend against the smart card stolen attack, and has some very bad design defects, making it unpractical. Thus, to design a truly secure authentication scheme for satellite communication systems, this paper presents a new scheme, making use of the advantages of elliptic curve cryptography and symmetric cryptography. The security analyses by the widely used BAN logic and heuristic discussions demonstrate that our new scheme possesses perfect security properties and can defend against various well‐known malicious attacks. Moreover, our new scheme allows users to update passwords locally in accordance with their wishes, achieving a good user experience. 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 three‐party password‐based key exchange protocol, a client is allowed to share a human‐memorable password with a trusted server such that two clients can negotiate a session key to communicate with each other secretly. Recently, many three‐party password‐based key exchange protocols have been developed. However, these proposed schemes cannot simultaneously achieve security and efficiency. Based on elliptic curve cryptography (ECC), this paper will propose a new simple three‐party password‐based authenticated key exchange scheme. The proposed method not only reduces computation cost for remote users and a trusted server but also is more efficient than previously proposed schemes. It is better suited for resource constrained devices, such as smart cards or mobile units. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Security is an essential requirement in any data communication system because a cyber criminal might try to break into it at any point by any means possible. A key agreement procedure is a necessary technique to ensure the security of data communication by way of encryption and mutual authentication. This article proposes a simple key agreement scheme on the basis of chaotic maps for VSAT satellite communications. The new scheme keeps the advantages of all chaotic maps‐based public key cryptosystems, providing a secure function of session key agreement. Based on the intractability of chaotic map discrete logarithm problem and chaotic map Diffie–Hellman problem, the security of this new scheme has been proven to be robust enough against all the well‐known cryptographical attacks with perfect forward secrecy provided. In addition, compared with similar schemes that serve the same purposes, the proposed scheme demands a lower computation cost. With all the previous features put together, the proposed scheme is extremely suitable for the use in very small aperture terminal satellite communication environments.
