摘要: 在计算Diffie-Hellman问题的困难性假设下,结合布隆过滤器的特性,采用无证书公钥密码体制的私钥生成原理,提出一种带权限的身份认证方案,并在标准模式下给出安全性证明。分析结果表明,该方案能有效解决权限问题,抵抗重放攻击和冒充攻击,防止篡改权限。

Abstract: Based on secret key generation technique of the certificateless public-key cryptosystem and features of Bloom Filter, an efficient ID-based identification scheme with privilege is presented under Computational Diffie-Hellman Problem(CDHP) assumption. Under standard mode, the scheme is proved that it is secure. Analysis result shows that the scheme not only can overcome domain user, but also can be against playback attack, impersonation attack and modification privilege.

Key words: identification scheme, provably security, Bloom Filter, random oracle mode
