CRYPTOGRAPHIC SYSTEM AND METHOD

A system for cryptographic processing comprises message unit (1, 7, 12) for providing a first message representation (3, 6, 11), wherein the first message representation is a representation of a message. The system comprises key unit (2) for providing a key representation (4, 9, 14), wherein the key...

Summary:A system for cryptographic processing comprises message unit (1, 7, 12) for providing a first message representation (3, 6, 11), wherein the first message representation is a representation of a message. The system comprises key unit (2) for providing a key representation (4, 9, 14), wherein the key representation is an encrypted representation of a first key of a first cryptographic algorithm and a second key of a second cryptographic algorithm, wherein the first cryptographic algorithm is different from the second cryptographic algorithm. The system comprises step unit (5, 10, 15) for performing a step of the first cryptographic algorithm and a step of the second cryptographic algorithm based on the first message representation (3, 6, 11) and the key representation, to obtain a second message representation (6, 11, 16).
