perfect forward secrecy

基本解釋

The new scheme provides implicit key authentication and perfect forward secrecy etc.
該方案提供了隱含密鑰認(rèn)證和完善前向保密等安全屬性。
In order to achieve perfect forward and perfect backward secrecy, and to counteract cryptoanalysis, the group session keys should be rekeyed.
為達(dá)到完美向前和完美向后保密以及對(duì)付密碼分析，需要更新組會(huì)話密鑰。
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(jià)值在于它能夠提供完美前向隱藏--當(dāng)驗(yàn)證方式被破壞的情況下，狀態(tài)密鑰不會(huì)被覆蓋(比如，當(dāng)有人獲取服務(wù)器私有密鑰的情況)。

perfect -forward secrecy 完整轉(zhuǎn)發(fā)安全性;和完整轉(zhuǎn)發(fā)安全性;完全轉(zhuǎn)發(fā)保密
