We analyze an algebraic representation of AES−128 as an embedding in BES, due to Murphy and Robshaw. We present two systems of equations S and K concerning encryption and key generation processes. After some simple but rather cumbersome substitutions, we should obtain two new systems C1 and C2. C1 has 16 very dense equations of degree up to 255 in each of its 16 variables. With a single pair
