Patent

CA 2641215

A secure communication platform on an integrated circuit is a highly integrated security processor which incorporates a general purpose digital signal processor (DSP) (62), along with a number of high performance cryptographic function elements, as well as a PCI and PCMCIA (14) 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 (28).

Une plateforme de communication sécurisée sur un circuit intégré constitue un processeur de sécurité hautement intégré qui comprend un processeur de signal numérique polyvalent (62), des éléments de fonction cryptographique haute performance, ainsi qu'une interface PCI et PCMCIA (14). La plateforme de communication sécurisée est intégrée à un processeur de signal numérique commercial, de sorte qu'un fournisseur qui s'intéresse au traitement des signaux numériques pourrait également recevoir des fonctions de sécurité intégrées compatibles avec ce processeur. Le circuit intégré comprend une bibliothèque de commandes cryptographiques et des algorithmes de chiffrement. Un processeur de chiffrement est fourni pour le chiffrement de clés et de données, de même qu'un processeur de hachage haute performance et un accélérateur de clés publiques (28).
