Abstract:
A cryptographic hardware accelerator identifies a mapped input bit sequence by applying a mapping transformation to an input bit sequence retrieved from memory and represented by a first element of a finite-prime field. The mapped input bit sequence is represented by a first element of a composite field. The accelerator identifies a mapped first key by applying the mapping transformation to an input key represented by a second element of the finite-prime field. The mapped first key is represented by the second element. The accelerator performs, within the composite field, a cryptographic round on the mapped input bit sequence using the mapped first key during a first round of the at least one cryptographic round, to generate a processed bit sequence. The accelerator identifies an output bit sequence to be stored back in the finite-prime field by applying an inverse mapping transformation to the processed bit sequence.

Claim (Index 6):
The processing system of  claim 1 , wherein the composite field includes 4-bit circuitry, and wherein the finite-prime field is represented by a GF(2 8 ) Galois field and the composite field is represented by a GF(2 4 ) 2  Galois field.
