中文摘要	匿名凭证系统和假名系统都是实现匿名认证的重要工具，但目前为止，这两种系统的经典构造方案在实际应用中仍有局限。对于属性公开的应用场景，经典的匿名凭证系统过于复杂，效率太低。假名系统虽然简单易用，但是其可关联性会泄露用户的行为习惯等隐私，都不适用于此类场景。针对该类应用场景，基于平滑投影散列函数构造一个匿名系统，可以实现属性公开条件下的凭证证明，在实现用户属性认证的同时实现会话密钥传输。用户只需要常数次的计算，并且可以规约到经典的安全性假设，在这种场景中具有更强的实用性。 Anonymous credential system and pseudonyms system are all the important tools for anonymous authentication,but the classic construction schemes of both systems have their limitations in practical applications up to now.In application scenarios of attributes open,the classic anonymous credential system is too complex and inefficient.Although the pseudonym system is easy to use,but its relevance may discloses user’s privacy of behaviour habits,so both systems are not suitable for such application scenes.As for such scenarios,we give an anonymous credential system based on smooth projective hash function.It is able to achieve credential proof on the condition of attributes open.The system could achieve session key transportation along with user’s attribute authentication.User only needs constant computation and the system could be reduced to standard security assumptions.These characters make our anonymous credential system more practical in such application scenario.
