网络认证技术是在计算机网络安全中有效解决身份安全和确认操作者身份安全而产生的方法,因为计算机网络世界中的身份验证信息都是用一组特定的数据来表示,所有对用户的授权也是针对用户数字身份来识别的。本文就如何保证网络数字身份认证与操作者的物理身份相对应的安全要求,阐述认证安全技术的类别方式和所使用的安全加密形式。作为防护网络安全的第一道关口,身份认证在网络保护过程中有着举足轻重的作用。 Network authentication technology is an effective way to solve identity security and confirm operator identity security in computer network security. Because the authentication information in the computer network world is represented by a specific set of data, all user authorization is Identified against the user’s digital identity. In this paper, how to ensure the network security requirements of the digital identity authentication and the operator’s physical identity, and explain the types of authentication security technology and the type of security encryption used. As the first gateway to the protection of network security, authentication plays a decisive role in the network protection process.
