A message of <2(64) bits is input to SHA, which produces a message digest of 160 bits, which is then fed to DSA. This describes what standard?
|
DSS from NIST. The Digital Signature Standard.
|
|
|
An attack on a hash that attempts to find a collision based on the probability that two different messages using the same hash function will produce the same message digest.
|
Birthday attack
