Patent

CA 2687822

The invention relates to the general field of digital security and more particularly cryptography. It proposes in particular a device and a method for encrypting a data sequence. The invention also relates to a cryptographic device (1) and method for generating a pseudo-random data sequence (13) and their favoured use in the field of digital security, namely in particular for data encryption and decryption and for the cryptographic hashing of messages.

L'invention se rapporte au domaine général de la sécurité numérique et plus particulièrement de la cryptographie. Elle propose notamment un dispositif et un procédé de chiffrement d une séquence de données. L invention concerne également un dispositif (1) et un procédé cryptographiques de génération d une séquence de données pseudo- aléatoire (13) et ainsi que leur utilisation privilégiée dans le domaine de la sécurité numérique, à savoir notamment pour le chiffrement et le déchiffrement de données et pour le hachage cryptographique de messages.
