网络信息交换的OTP认证技术

The OTP mechanism in the network information exchange

在开发防火墙系统以及实现防火墙与内部网络安全管理子系统之间的数据交换时 ,要用到身份认证和加密技术 .本文主要介绍了用 OTP机制实现身份认证 ,为了保证信息的安全性 ,还介绍了实现初始密钥交换和数据加密技术 。

The technology of authentication and encryption have been used when we designed the firewall system and its message exchange with the security sub system of network management. This paper discusses the OTP authentication mechanism and introduces the public key and the symmetric key technology respectively for the security of exchanged information when initial key exchange and data transportation are used. Finally, it gives out a concise conclusion.
