Abstract:
1. A method for encrypting a data sequence, comprising the steps of: generating, by an electronic circuit, a payload data sequence comprising a plurality of first digits expressed as members of a Galois field GF[p generating, by an electronic circuit, an encryption sequence comprising a plurality of second digits expressed as members of said Galois field GF[p mapping, by an electronic circuit, said payload data sequence and said encryption sequence from said Galois field GF[p generating, by an electronic circuit, an encrypted data sequence by performing a CGFC arithmetic process, said CGFC arithmetic process including combining first results of said first Affine transformation with second results of said second Affine transformation; wherein said first results and said second results are combined using a Galois field multiplication operation in said Galois extension field GF[p
