| 摘 要： | 身份认证是信息安全理论和技术中非常重要的方面.通常认证最大的问题是用户名和口令都以明文的方式在网络中传输,所以安全性不高,极易遭受重放攻击和字典攻击.而OTP与Kerberos协议相结合的认证技术更能够避免常用OTP技术存在的易受小数攻击的安全漏洞.

| Abstract: | Authentication plays an important role in the theory and technique of information security.In traditional authentication,users' names and passwords are transferred in plaintext,which is the most serious problem.It cannot resist dictionary and play back attack.OTP/Kerberos makes the user and the server to authenticate each other,and also prevents crasher from small number attack. |
