Abstract
Identity-based cryptography is a rapidly emerging approach to public-key cryptography that public keys can be arbitrary identifiers. Analyzing the existing identity-based authenticated encryption scheme which a weakness is presented-a recipient can pretend other users to send messages to him,that is,users can't authenticate whether a message's sender is true,and combining bilinear pair,an improvement of that scheme is proposed,whose security is based on the bilinear Diffie-Hellman problem. The security and efficent are analyzed. The result shows that the scheme not only overcomes the mentioned weakness ,but also keeps the excellence of that scheme.关键词
