Properties of the Transformation Semigroup of the Solitaire Stream Cipher

Boris Pogorelov and Marina Pudovkina

Abstract: Stream ciphers are often used in applications where high speed and low delay are a requirement. The Solitaire stream cipher was developed by B. Schneier as a paper-and-pencil cipher. Solitaire gets its security from the inherent randomness in a shuffled deck of cards. In this paper we investigate semigroups and groups properties of the Solitaire stream cipher and its regular modifications.
