安全性

We propose a dynamic identity authentication scheme through a theorem about relative prime numbers, which can prevent replay attacks from taking place. In addition, we present a threshold signature scheme without a trusted party by use of joint secret sharing technique. Finally, the security flaw in an enhanced password authentication scheme is pointed out and the security of an enhanced key agreement protocol is analyzed.

首先基于一个关于互素数的定理设计了一个动态身份认证协议，该协议使攻击者不可能通过回放攻击来假冒用户；利用联合秘密共享技术设计了一个无可信中心门限签名方案；最后，分析了一个改进的身份认证协议存在的安全漏洞，以及一个改进的密钥协商协议的安全性。

Related to real application adn by means of the character that int28 idle call is excuted cyclically when DOS kernel waits to input and output, rear program is used as Int28 interrupt service program.So rear I/O operation can be competely controlled by DOS. And thus system security is ensured.

结合具体应用，利用DOS内核在等待输入输出时循环执行INT28空闲调用这一特点，将后台程序作为INT28中断服务程序，实现了后台I／O操作完全在DOS控制下进行，从而保障了系统的安全性。
