BDN-GWMNN: Internet of Things (IoT) Enabled Secure Smart City Applications

Nowadays, next-generation networks such as the Internet of Things (IoT) and 6G are played a vital role in providing an intelligent environment. The development of technologies helps to create smart city applications like the healthcare system, smart industry, and smart water plan, etc. Any user accesses the developed applications; at the time, security, privacy, and confidentiality arechallenging to manage. So, this paper introduces the blockchain-defined networks with a grey wolf optimized modular neural network approach for managing the smart environment security. During this process, construction, translation, and application layers are created, in which user authenticated based blocks are designed to handle the security and privacy property. Then the optimized neural network is applied to maintain the latency and computational resource utilization in IoT enabled smart applications. Then the efficiency of the system is evaluated using simulation results, in which system ensures low latency, high security (99.12%) compared to the multi-layer perceptron, and deep learning networks.

     

Secure and Efficient Mutual Authentication Scheme for NFC Mobile Devices

As the technology of mobile devices spreads fast, the price of mobile devices is getting cheaper. Most of the people have mobile devices, and these devices have the technology of near field communication (NFC). With the long time development and research, the mobile devices use NFC technology on the payment and authentication applications, and replace the smartcard, the access control card, and the credit card by using the card emulation mode. It helps the development of NFC applications. In recent years, more and more users begin using NFC technology on mobile payment and authentication. Many researches have proposed the related NFC authentication protocols, but their schemes are still lack of some security properties and functions, which are necessary for NFC authentication protocols. In this paper, we propose a secure and efficient NFC authentication scheme between two NFC devices by the help of the authentication server that provides mutual authentication.     

Secure Data Access and Sharing Scheme for Cloud Storage

Cloud storage is a new storage mode emerged along with the development of cloud computing paradigm. By migrating the data to cloud storage, the consumers can be liberated from building and maintaining the private storage infrastructure, and they can enjoy the data storage service at anywhere and anytime with high reliability and a relatively low cost. However, the security and privacy risks, especially the confidentiality and integrity of data seem to be the biggest hurdle to the adoption of the cloud storage applications. In this paper, we consider the secure data access and sharing issues for cloud storage services. Based on the intractability of the discrete logarithm problem, we design a secure data access and data sharing scheme for cloud storage, where we utilize the user authentication scheme to deal with the data access problem. According to our analysis, through our scheme, only valid user with the correct password and biometric can access to the cloud storage provider. Besides, the authorized users can access the rightful resources and verify the validity of the shared data, but cannot transfer the permission to any other party. At the same time, the confidentiality and integrity of data can be guaranteed.

A Secure Path Selection Scheme for Mobile Ad Hoc Network

Mobile ad hoc network is open medium, infrastructure-less and easy to install. Despite these features, mobile ad hoc network is vulnerable to various security attacks. Black hole and gray hole security attacks outrank among all security attacks. This paper proposes a distributed delegation-based scheme, namely, a secure path selection scheme. The proposed scheme identifies and allows only trusted nodes to become part of active path.

A User-Centric Data Secure Creation Scheme in Cloud Computing

Due to the use of the cloud computing technology, the ownership is separated from the adminis-tration of the data in cloud and the shared data might be migrated between different clouds, which would bring new challenges to data secure creation, especially for the data privacy protection. We propose a User-centric data secure creation scheme (UCDSC) for the security requirements of resource owners in cloud. In this scheme, a data owner first divides the users into different domains. The data owner encrypts data and defines different secure managing poli-cies for the data according to domains. To encrypt the data in UCDSC, we present an algorithm based on Access con-trol conditions proxy re-encryption (ACC-PRE), which is proved to be master secret secure and Chosen-ciphertext attack (CCA) secure in random oracle model. We give the application protocols and make the comparisons between some existing approaches and UCDSC.     

An Ownership Transfer Scheme Using Mobile RFIDs

RFID reader equipment is widely used in hand-held devices; thus, the security of the connection between mobile readers and RFID servers is an important issue. In this paper, we propose a novel scheme with low implementation costs and conforming to EPC C1G2 standards. The benefits include reducing the manpower required for market management, market members using the mobile readers to query product information, as well as ensuring secure and efficient cash transactions. The membership can also access after-sales service or make ownership transfers with other users. Moreover, in order to achieve mutual authentication, our proposed scheme integrates fingerprint biometrics, related cryptology and a hash function mechanism to ensure the security of the transmitted messages.

Incorporating Data from Multiple Sensors for Localizing Nodes in Mobile Ad Hoc Networks

The ad hoc network localization problem deals with estimating the geographical location of all nodes in an ad hoc network, focusing on those nodes that do not have a direct way (for example, GPS) to determine their own location. Proposed solutions to the ad hoc localization problem (AHLP) assume that nodes are capable of measuring received signal strength indication (RSSI) and/or are able to do coarse (sectoring) or fine signal angle-of-arrival (AoA) measurements. Existing algorithms exploit different aspects of such sensory data to provide either better localization accuracy or higher localization coverage. However, there is a need for a framework that could benefit from the interactions of nodes with mixed types of sensors. In this paper, we study the behavior of RSSI and AoA sensory data in the context of AHLP by using both geometric analysis and computer simulations. We show which type of sensor is better suited for which type of network scenario. We study how nodes using either, both, or none of these sensors could coexist in the same localization framework. We then provide a general particle-filtering framework, the first of its kind, that allows heterogeneity in the types of sensory data to solve the localization problem. We show that, when compared to localization scenarios where only one type of sensor is used, our framework provides significantly better localization results. Furthermore, our framework provides not only a location estimate for each nonanchor, but also an implicit confidence measure as to how accurate this estimate is. This confidence measure enables nodes to further improve on their location estimates using a local, iterative one-hop simple message exchange without having to rely on synchronized multiphase operations like in traditional multilateration methods.
