CRYPTOGRAPHIC METHODS AND DEVICES FOR PSEUDO-RANDOM GENERATION, ENCRYPTING DATA, AND CRYPTOGRAPHICALLY HASHING A MESSAGE

摘要

CRYPTOGRAPHIC METHODS AND DEVICES FOR PSEUDO-RANDOMGENERATION, ENCRYPTING DATA, AND CRYPTOGRAPHICALLYHASHING A MESSAGEThe invention relates to the general field ofdigital security and more particularly cryptography. Inparticular it proposes a device and a method ofencrypting a sequence of data. The invention alsorelates to a cryptographic device (1) and a cryptographicmethod of generating a pseudo-random data sequence (13)and their favored use in the field of digital security,in particular for encrypting and decrypting data and forcryptographically hashing messages.
