PFS: Perfect Forward Secrecy or Public-Key Forward Secrecy

In an authenticated key agreement protocol that uses public key cryptography, perfect forward secrecy (or PFS), also known as Public-Key Forward Secrecy, is the property that disclosure of the long-term secret keying material that is used to derive an agreed ephemeral key does not compromise the secrecy of agreed keys from earlier runs.
