In an Information-Centric Internet of Things (ICIoT) environment for big data sharing, IoT data can be cached throughout the network. Such distributed data caching poses a challenge on flexible authorization and identity verification. For fine-grained data access authorization in a distributed manner, Ciphertext-Policy Attribute-Based Encryption (CP-ABE) has been identified as a promising approach...
In Vehicular Ad hoc NETworks (VANETs), authentication is a crucial security service for both inter-vehicle and vehicle-roadside communications. On the other hand, vehicles have to be protected from the misuse of their private data and the attacks on their privacy, as well as to be capable of being investigated for accidents or liabilities from non-repudiation. In this paper, we investigate the authentication...
In Vehicular Ad hoc Networks (VANETs), authentication is a crucial security requirement to avoid attacks to both inter-vehicle and vehicle-roadside communication. Vehicles have to be prevented from the misuse of their private data and the attacks on their privacy. In this paper, we investigate the authentication and privacy issues in VANETs. We propose a novel ID-based authentication framework with...
Broadcast authentication plays an important role in wireless sensor networks. In this paper, we propose key predistribution based broadcast authentication scheme. In the scheme the base station can derive all keys used for broadcast authentication from initial parameters and sensor nodes are just able to deduce keys excluding authentic keys from initial parameters stored before deployment according...
In this article, the security system of WLAN and security measure of WLAN in which IEEE 802.11 series are used as standard of communications is introduced. The defects of security system which is used now are analyzed and the projects for improving the security system which is used now are put forward.
