Experimenting with Shuffle Block Cipher and SMT Solvers

Martin Stanek

Abstract: We experiment with the block cipher proposed by Hoang, Morris, and Rogaway, even though the cipher is insecure. The cipher is based on swap-or-not shuffle, and we call it the Shuffle Block Cipher. We show how the cipher can be translated into SMT-LIB v2 format, suitable for automated solving by SMT solvers. We compare performance of various SMT solvers on the encryption and known plaintext attack problems.
