摘要： 传统的认证有两种方式：对称密码机制（基于共享秘密）和非对称密码机制，但两种各有优缺点。在具体应用中设计了一种结合对称密码体制和非对称密码体制的混合认证体制，这种认证体制有着明显优于原来两种体制的特点。

Abstract: A fundamental concern in building a secure distributed system is authentication of local and remote entities in the system. We survey two typical models of authentication which are based on the technology of symmetric and asymmetric cryptographic technologies respectively. We analysis these two models and present a new one which encompasses all the virtues of them.
