Perfect Forward Secrecy (PFS)

To establish a secure communication channel, two parties often negotiate on a new session key for each new communication session. To secure this communication establishment phase long term keys may be used.
PFS denotes the property of key-agreement protocols which generate a session key that is still secure even when the long term keys are exposed. The Diffie–Hellman key exchange may be used for this purpose.
