Propiedad de
un sistema de cifra que nos garantiza que las claves usadas hoy no se verán
descubiertas si el día de mañana se revela alguna información secreta
relacionada con dichas claves.
(I) For a key
agreement protocol, the property that compromises long-term keying material
does not compromise session keys that were previously derived from the
long-term material. (Compare: public-key forward secrecy.) [RFC4949:2007]
the property that
knowledge of As long-term private key subsequent to a key agreement operation
does not enable an opponent to recompute previously derived keys.
[ISO-15946-3:2002]
the property that
knowledge of As long-term private key or knowledge of Bs long-term private key
subsequent to a key agreement operation does not enable an opponent to
recompute previously derived keys. [ISO-15946-3:2002]
the property that
knowledge of both As and Bs long-term private keys subsequent to a key
agreement operation does not enable an opponent to recompute previously derived
keys. [ISO-15946-3:2002]
A cryptosystem in
which, if one encryption key is compromised, only the data encrypted by that
specific key is compromised. Some cryptosystems allow keys to be derived from
previous keys, so that if the first key is compromised, an attacker might have
enough information to figure out other keys and/or decrypt data encrypted using
those keys.
