perfect forward secrecy

基本解释

The new scheme provides implicit key authentication and perfect forward secrecy etc.
该方案提供了隐含密钥认证和完善前向保密等安全属性。
In order to achieve perfect forward and perfect backward secrecy, and to counteract cryptoanalysis, the group session keys should be rekeyed.
为达到完美向前和完美向后保密以及对付密码分析，需要更新组会话密钥。
Ephemeral DH is valued because it provides perfect forward secrecy -- the session keys cannot be recovered if the authentication method is broken (e.g., someone retrieves the server's private key).
EDH的价值在于它能够提供完美前向隐藏--当验证方式被破坏的情况下，状态密钥不会被覆盖(比如，当有人获取服务器私有密钥的情况)。
