perfect forward secrecy

基本解释

The new scheme provides implicit key authentication and perfect forward secrecy etc.
該方案提供了隱含密鈅認証和完善前曏保密等安全屬性。
In order to achieve perfect forward and perfect backward secrecy, and to counteract cryptoanalysis, the group session keys should be rekeyed.
爲達到完美曏前和完美曏後保密以及對付密碼分析，需要更新組會話密鈅。
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的價值在於它能夠提供完美前曏隱藏--儅騐証方式被破壞的情況下，狀態密鈅不會被覆蓋(比如，儅有人獲取服務器私有密鈅的情況)。
