基于IDEA加密的身份认证模型的研究与设计

The Research and Design of LAN OTP Authentication Model Based on IDEA Encr yption

就信息资源保护的需求现状,分析了当前网络信息安全通常采用的技术以及身份验证技术现状。介绍了OTP原理和对称加密算法IDEA。在此基础上给出了基于IDEA加密的OTP局域网认证系统的设计与实现,从而保证认证信息的加密传输,提高认证系统的安全系数。

Based on the demand status of the information resour ce ,analyses the network information security technique and the current status of authentication system. It introduces the principle of OTP and the symmetrical en cryption arithmetic of IEDA. At the end, gave one method to design and implement ation of the LAN OTP authentication system based on IDEA encryption. It can ensu re th e encryption transmitting of the authentication information and increase the sec urity of the authentication system.
