In an authenticated key-agreement protocol that uses public key cryptography, perfect forward secrecy (or PFS) is the property that ensures that a session key derived from a set of long-term public and private keys will not be compromised if one of the (long-term) private keys is compromised in the future. Forward secrecy has been used as a synonym for perfect forward secrecy [1], since the term perfect has been controversial in this context.
