Improved ID-based security framework for ad hoc network

As mobile devices with wireless communication capacity become more and more popular, the study on ad hoc networks that offer convenient infrastructure-free communication has arose the attention from both the academic and the industry. However, the previous security schemes proposed for ad hoc networks either suffer from the structure support problems or have security flaws. This paper examines the weaknesses of a Bohio-Miri's recent work, and then proposes our new schemes to enhance the security and the performance. The security of the proposed protocols is proved in the random oracle model. (C) 2006 Elsevier B.V. All rights reserved.
