| Abstract(in English) | Various attacks against RC5 have been analyzed intensively. A known plaintext attack has not been reported that it works on so higher round as a chosen plaintext attack, but it can work more efficiently and practically. In this paper we investigate a known plaintext attack against RC5 by improving a correlation attack. Our known plaintext correlation attack can break RC5-32 with 10 rounds(20 half-rounds)with a success probability of 90% by using 2^<63.67) plaintexts. Furthermore our attack can break RC5-32 with 21 half-rounds in a success probability of 30% by using 2^<63.07> plaintexts. |
