Patent

CA 2303297

A secure communication platform on an integrated circuit is a highly integrated security processor which incorporates a general purpose digital signal processor (DSP), along with a number of high performance cryptographic function elements, as well as a PCI and PCMCIA interface. The secure communications platform is integrated with an off- the-shelf DSP so that a vendor who is interested in digital signal processing could also receive built-in security functions which cooperate with the DSP. The integrated circuit includes a callable library of cryptographic commands and encryption algorithms. An encryption processor is included to perform key and data encryption, as well as a high performance hash processor and a public key accelerator.

Une plate-forme de communications sécurisée sur un circuit intégré constitue un processeur à sécurité intégrée comprenant un processeur de signal numérique polyvalent (DSP), plusieurs éléments fonctionnels cryptographiques hautes performances, une interface PCI, et une interface PCMCIA. La plate-forme de communications sécurisée est intégrée à un processeur de signal numérique du commerce, de façon qu'un revendeur se préoccupant de traitement de signal numérique puisse également recevoir les fonctions de sécurité intégrée coopérant avec le processeur de signal numérique. Le circuit intégré comporte une bibliothèque consultable de commandes cryptographiques et d'algorithmes de cryptage. L'invention concerne également un processeur de cryptage opérant au niveau clé et données, ainsi qu'un processeur d'adressage calculé hautes performances et un accélérateur à clé publique.
