p {margin: 0; padding: 0;} MD5 (message Degest Algerithm Security of Hash values and MAC RIPE MD - -160 - it is developed under the European RACE integrity Primitives Evaluation Project (RIPE) - MD - message digest SHA 1 and RIPE MP gives the hask code - 160. 1 MAC value has a property called compulational-resistance Given one or more text MAC Pairs (xi, CK(2))), it is computationally infeasible to compute any tent MAC pair (x, G (x)) for any new input x # xi. Eg: Key size = K bits 1 known text. - MAC Pair compute R bit MAC on known tent for all keys. Atleast one key should Produce the correct text - MAC pair. Effort taken = 2K
