The primary goal of the secure socket layer protocol (SSL) is to provide confidentiality and data integrity between two communicating entities. Since the most computationally expensive step in the SSL handshake protocol is the server's RSA decryption, it is introduced that the proposed secret exchange algorithm can be used to speedup SSL session initialization. The optimization strategy, which is...
In existing clustering algorithms in mobile ad hoc networks, some of them consider only stability of cluster heads, and some others take only security into account, while only a few of them consider both factors. We propose Voting-based Clustering Algorithm with subjective trust and stability (VCA) by accessing subjective trust of node through Bayesian method and by evaluating stability of node through...
This paper analyzes the problems within current anti-spoofing mechanisms and proposes a new SSL protected trust model. Then, this paper describes the attacks on SSL protected trust model. This paper also proposes the new automatic detecting security indicator (ADSI) scheme to defend against spoofing attacks on SSL protected Web servers. This paper describes the ADSI-based trust model. In a secure...
Traditional subjective logic provides a specific belief calculus that uses opinion to express beliefs, but it does not support the time property. In the heterogeneous, dynamic, and open networks such as the Internet, we propose a time-related trust model based on subjective logic theory. The proposed model consists of two additional factors compared with the traditional one: a time-related attenuation...
In this paper, we propose a novel 2-way handshake authentication protocol to locally authorize intra-domain roaming users for efficient authentication in mobile IP networks, which is based on authentication, authorization and accounting (AAA) architecture. The performance evaluation shows that our protocol outperforms the existing authentication protocols.
Distributed authentication has the property of high security compared with existing authentication schemes. However, its success ratio for authentication may be not high, especially in large-scale Mobile Ad- Hoc Networks (MANETs). In order to address this issue, we propose a hybrid authentication scheme which integrates the chained authentication with the distributed authentication. When a node can't...
