Abstract. Given two simplicial complexes C1 and C2 embedded in Euclidean space IRd , C1 subdivides C2 if (i) C1 and C2 have the same underlying space, and (ii) every simplex in C1 ...
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 gen...
