In this paper we show a drastic improvement of these results due to a novel . differential approach. Our attack requires 244 chosen plaintexts. We show that the 64 b

For this purpose, it uses intermediate feedbacks that the attacker cannot control, choosing them as a keyed OFB stream, independent of the plaintexts and ciphertexts. The attack we describe finds a way to use ev

From , to Yak: Change in a Sherpa Villageon key to an unauthorized user (pirate). This paper first derives lower bounds on the sizes of keys and ciphertexts. These bounds are all tight because an optimum one-time use scheme is also presented. We then propose a multiple-use scheme which approximately meets our bounds. This scheme is proven

By this implementation we set a record with . consisting of 85 decimal digits. With regard to computational results, including the running ti
