Title (EN) INLINE CRYPTOGRAPHIC ENGINE (ICE) FOR PERIPHERAL COMPONENT INTERCONNECT EXPRESS (PCIE) SYSTEMS
(FR) MOTEUR CRYPTOGRAPHIQUE EN LIGNE (ICE) POUR DES SYSTÈMES D'INTERCONNEXION DE COMPOSANTS PÉRIPHÉRIQUES EXPRESS (PCIE)
Abstract:
(EN) Aspects disclosed in the detailed description include inline cryptographic engine (ICE) for peripheral component interconnect express (PCIe). In this regard, in one aspect, an ICE is provided in a PCIe root complex (RC) in a host system. The PCIe RC is configured to receive at least one transport layer packet (TLP), which includes a TLP prefix, from a storage device. In a non-limiting example, the TLP prefix includes transaction-specific information that may be used by the ICE to provide data encryption and decryption. By providing the ICE in the PCIe RC and receiving the transaction-specific information in the TLP prefix, it is possible to encrypt and decrypt data in the PCIe RC in compliance with established standards, thus ensuring adequate protection during data exchange between the PCIe RC and the storage device.
(FR) Selon certains aspects, la présente invention concerne un moteur cryptographique en ligne (ICE) pour une interconnexion de composants périphériques express (PCIe). Selon un aspect, un ICE est situé dans un complexe de racine (RC) de PCIe dans un système hôte. Le RC PCIe est conçu pour recevoir au moins un paquet de couche transport (TLP) comprenant un préfixe de TLP, d'un dispositif de mémorisation. Dans un exemple non limitatif, le préfixe de TLP comprend des informations spécifiques de transaction pouvant être utilisées par l'ICE afin d'assurer un chiffrement et un déchiffrement de données. Grâce à la présence de l'ICE dans le RC PCIe et à la réception des informations spécifiques de transaction dans le préfixe de TLP, il est possible de chiffrer et de déchiffrer des données dans le RC PCIe conformément à des normes établies, ce qui permet d'assurer une protection adéquate pendant un échange de données entre le RC PCIe et le dispositif de mémorisation.
