https://doi.org/10.1007/978-2-8178-0379-1bits, and a linear attack with 2. known plaintexts can find 7 key bits. This suggests that it is not safe to reduce the number of rounds in order to improve the performance. Moreover, it is shown that the final permutation has some cryptographic significance in the CFB mode.

The security of the schemes presented is unconditional, since they are not based on any computational assumption. We give bounds on the size of the shares held by participants and on the site of the broadcast message in such schemes.

We also present some conservative extrapolations to estimate the difficulty of factoring even larger numbers, using either the quadratic sieve method or the number field sieve, and discuss the issue of the crossover point between these two methods.

Modular exponentiation constitutes the basis of many well known and widely used public key cryptosystems. A fast and portable modular exponentiation will considerably enhance the speed and applicability of these systems.
