An Efficient Authentication and Simplified Certificate Status Management for Personal Area Networks

摘要

Recently the concept of personal PKI was introduced to describe a public key infrastructure specifically designed to support the distribution of public keys in a personal area network. However, traditional public key signature schemes and certificate status management schemes used in the personal PKI concept cause formidable overheads to components in the personal area network since mobile devices constituting the personal area network have limited computational and communication capabilities. In this paper we propose an efficient authentication protocol that eliminates the traditional public key operations on mobile devices without any assistance of a signature server. Moreover, the proposed protocol provides a simplified procedure for certificate status management to alleviate communication and computational costs on mobile devices in the personal area network.
