普适环境中基于身份的跨域认证方案
Identity-based cross-domain authentication scheme in pervasive computing environments
摘要
Abstract
An identity-based signature scheme was proposed based on additive elliptic curve group. The verification result of the signature was a constant with respect to the signer's identity. The scheme could guarantee user anonymity in the process of cross-domain authentication and avoided the pairing operation. Then a cross-domain authentication scheme was constructed by combining the proposed signature scheme. During the authentication, a user constructed the signature of timestamp as authentication proof, which realized secure cross-domain authentication and user anonymity. It is shown that the proposed scheme has superiority in both security and efficiency, and is more suitable for pervasive computing.关键词
