认证在网络应用和安全领域中起着非常重要的作用,是保证系统安全的重要措施之一。传统的单向认证机制能够确保安全领域中外部系统的合法性,但无法保证接入系统的合法性。由此提出了双向认证机制,并介绍了双向认证的基本原理和主要算法,最后对双向认证机制的安全性作了分析,并构造了双向认证机制的应用模型。
Certification plays a very important role in the field of network applications and security and is one of the important measures to ensure system security. The traditional one-way authentication mechanism can ensure the legitimacy of external systems in the field of security, but can not guarantee the legitimacy of the access system. The bidirectional authentication mechanism is proposed. The basic principle and main algorithms of bidirectional authentication are introduced. Finally, the security of bidirectional authentication mechanism is analyzed and the application model of bidirectional authentication mechanism is constructed.
