基于TEA算法的企业网动态口令安全系统研究

Research on dynamic password security system for enterprise office network based on TEA algorithm

提出一个基于TEA加密算法和短信息动态口令+用户静态口令的企业办公网双因子安全体系系统。该系统通过架构短信息服务器平台,由TEA算法生成动态口令并对其实现加密、解密过程;以短信形式将动态口令发送到用户手机,用户利用收到的动态口令+用户名和用户密码登陆办公网。该系统无须改变企业现有网络架构,可有效验证用户身份的合法性,提高企业办公网的安全性。

A two-factor security system for enterprise office network based on Tiny Encrypt Algorithm（TEA） plus the SMS dynamic password and the user＇s static password is proposed in this paper.This system sets up a short message service platform,randomly creates dynamic password by the TEA algorithm and accomplishes encryption or encoding processing to this check code.This password is sent to user＇s mobile phone as the short message,and then user uses this dynamic password and user＇s static password to login on the office network.This system need not change existing system architecture of enterprise office network,and can increase the security level of enterprise＇s network and verify the user＇s legitimacy effectively.
