ConSum v0: An Experimental Cipher

We present an experimental block cipher, ConSum, based on a hitherto unstudied design element: the Conway transformation. ConSum features an extremely simple design and the ability to operate with arbitrary key lengths, block sizes and round numbers. We study it empirically and statistically so as to illustrate how it might be secure.

On Multiple Precision Based Montgomery Multiplication without Precomputation of N0´ = -N0-1 mod W

An efficient implementation of modular exponentiation, i.e., the main building block of many public key cryptographic devices, is achieved by algorithmic optimization of the Montgomery modular multiplication algorithm based on multiple precision such that pre-computation of N0 ́ = N0 -1 mod W can be avoided. This can be attained by modifications of the multiplier used.

On N0-Categorical Weakly o-Minimal Structures

@0-categorical o-minimal structures were completely described in 4], and are essentially built up from copies of the rationals as an ordered set by`cutting and copying'. Here we investigate the possible structures which an @0-categorical weakly o-minimal set may carry, and nd that there are some rather more interesting (and not o-minimal) examples. We show that even here the possibilities are l...
