Authentication and key distribution (AKD) protocols become more and more important in the design of wireless networks. The design criteria of the AKD protocols include the scalability, the communication efficiency, the computational efficiency and the robustness of security. In this paper, we first analyze the vulnerabilities of an AKD protocol for wireless networks under three types of attacks. Then,...
Three-party authenticated key exchange protocol (3PAKE) is an important cryptographic technique for secure communication which allows two parties to agree a new secure session key with the help of a trusted server. In this paper, we proposed a new three-party authenticated key exchange protocol which aims to achieve more efficiency with the same security level of other existing 3PAKE protocols. Security...
In order to speed up the propagating process, the worms need to scan many IP addresses to target vulnerable hosts. However, the distribution of IP addresses is highly nonuniform, which results in many scans wasted on invulnerable addresses. Inspired by the theory of good point set, this paper proposes a new scanning strategy, referred to as good point set scanning (GPSS), for worms. Experimental results...
Sensor networks are resource-constrained, which makes developing efficient key distribution scheme a challenging problem. In general, many key distribution techniques are designed to address the trade-off between limited resources and security, no key distribution technique is ideal to all the scenarios where sensor networks are used. In this paper, we primarily focus on storage requirements of several...
