Perfect Forward Secrecy

In cryptography, forward secrecy (also known as perfect forward secrecy or PFS) is a property of key-agreement protocols ensuring that a session key derived from a set of long-term keys cannot be compromised if one of the long-term keys is compromised in the future. The key used to protect transmission of data must not be used to derive any additional keys, and if the key used to protect transmission of data is derived from some other keying material, then that material must not be used to derive any more keys. In this way, compromise of a single key permits access only to data protected by that single key.

  • Facebook Tests Onion URL for Tor Users

    … available directly over Tor network at the following URL (which will only work in Tor-enabled browsers): https://facebookcorewwwi.onion/. Facebook’s onion address provides a way to access Facebook through Tor without losing the cryptographic protections provided by the Tor cloud.
