有效数字

In every policy, there must be some security authentication information,such as one policy Authorizer, one Licensee, one TimeStamp, one LifeTime and a digital Signature, and some policy management information:At last, this paper designs and implements a HywaveGuard models instance based on Windows OS.

每个策略都有策略发布者，接受者的证书，策略制定的时间戳及有效期，同时还要附上发布者的数字签名，这些信息用于保证策略的安全验证；每个策略还可包含策略管理命令及策略内容，这些信息用于保证有效的策略管理与节点间通信。最后，针对当前网络的实际情况，本文在Windows系统平台上设计与实现了HywaveGuard防火墙模型的一个实例。

We have to deliver most of their attention to the conventional approach to digital mode change and change is to be fully cope psychologically prepared for a smooth transition, find the implementation of an effective deterrent.

The plug-in has three advantages: First, each packet is authenticated by a One-time Signature, so there is no need for both sender and receiver maintain a buffer and there is no delay for signing and verifying and authentication failure of current packets do not effect the authentication of other packet. Second, we design a mechanism to regenerate Merkle Trees, so just only one normal digital signature signing operation is required to provide unlimited number of One-time Signature for signing unlimited length of

插件有如下特点：一、使用一次签名对每个包单独签名和认证，接发双方不需要缓存包，没有延迟，而且当前包的认证失败或者丢失不影响其他包的认证；二、设计了两颗树交替更新的机制，只需要开头一个普通数字签名，就能确保有效的一次签名能源源不断的生成，因此可对无限长的流签名；三、在包的层次上操作，因此可以处理任何流媒体类型。
