Title (EN) SPECULATIVE CRYPTOGRAPHIC PROCESSING FOR OUT OF ORDER DATA
(FR) TRAITEMENT CRYPTOGRAPHIQUE SPÉCULATIF POUR DES DONNÉES DÉSORDONNÉES
Abstract: front page image
(EN)In described examples, a data encryption system includes multiple encryption cores (302) to perform a variety of encryption, decryption or message authentication functions. An external memory interface includes a non-encrypted bus (305) and an encrypted bus (307) connected to an external memory. A speculative read crypto cache (304) is operable to store the full or partial results of any speculative crypto operation. A scoreboard (303) stores external memory read commands associated with any speculative crypto operation.
(FR)Dans les exemples décrits, l'invention concerne un système de chiffrement de données comprenant plusieurs noyaux de chiffrement (302) pour exécuter diverses fonctions de chiffrement, de déchiffrement, ou d'authentification de messages. Une interface de mémoire externe comprend un bus non chiffré (305) et un bus chiffré (307) connectés à une mémoire externe. Un cache cryptographique de lecture spéculative (304) est conçu pour stocker les résultats complets ou partiels d'une quelconque opération cryptographique spéculative. Un tableau de bord (303) stocke des commandes de lecture de mémoire externe associées à une quelconque opération cryptographique spéculative.
