The security of communications transmitted across the Internet can be improved by using public key cryptography. However if the public and private keys used in those communications are compromised it can reveal the data exchanged in that session as well as the data exchanged in previous sessions. ...
Perfect Forward Secrecy is used to improve the security of communications transmitted across the Internet using public key cryptography.
In Transport Layer Security (TLS), Diffie–Hellman key exchange-based PFSs (DHE-RSA, DHE-DSA) and elliptic curve Diffie–Hellman-based PFSs (ECDHE-RSA, ECDHE-ECDSA) are available. In theory, TLS can choose appropriate ciphers since SSLv3, but in everyday practice many implementations have ref...

through the use of public-key cryptography and wait until the underlying cipher is broken (e.g. large quantum computers could be created which allow the discrete logarithm problem to be computed quickly). This would allow the recovery of old plaintexts even in a system employing forward ...

—In the real world, cryptographic computations are often performed on a relatively insecure device which can not be trusted to maintain secrecy of the secret key. Exposure of secret keys is perhaps the most debilitating attack on a cryptosystem since it implies that all security guarantees are lo...

Perfect Forward Secrecy (PFS) is a key exchange technique inSSL/TLSsecurity protocols that prohibits attackers from decrypting data from previous or future sessions if they have the private keys used in each session. PFS makes use of ephemeral session keys that are unique to each session and dis...
