![]() ![]() With a MAC, keys K 1 and K 2 are identical (or can be trivially recomputed from each other). Verification: given the message m, a key K 2 and the MAC value or signature s, verify that they correspond to each other (the MAC value or signature is valid for the message m, using verification key K 2).Generation: given the message m and a key K 1, compute the MAC value or signature s.In both MAC and digital signature schemes, you have two algorithms: ![]()
