A high-performance encryption card and its communication method

Abstract

The present invention proposes a high-performance cryptographic card with high integration, including a cryptographic integrated chip, a random source module, a FLASH chip, a PCI-E interface and an intelligent cryptographic key, and the cryptographic integrated chip is internally integrated with a main processor unit and a cryptographic algorithm operation unit. , a peripheral interface unit, a BAR register, and a DMA controller; the cryptographic integrated chip is also provided with a BAR register and a DMA controller; the BAR register is also connected to an external host through the command logic channel, and receives the information issued by the external host Management instruction data, reconstructed cryptographic operators and DMA configuration data are stored in the register of the cryptographic algorithm operation unit; the DMA controller is connected to the external host through the operation logic channel, and the asymmetric The algorithm operation unit and the reconfigurable symmetric digest algorithm operation unit receive the cryptographic operation data issued by the external host and forward it to the asymmetric algorithm operation unit or the reconfigurable symmetric digest algorithm operation unit.

Description

technical field [0001] The invention relates to the technical field of high-performance cipher cards, in particular to a high-performance cipher card and a communication method thereof. Background technique [0002] With the rise of emerging technologies such as the Internet of Things, big data, and cloud computing, people are increasingly dependent on the network environment and network information resources. Computer networks have become an important guarantee for the development of today's information society. Network information security is related to the security of national sovereignty, social stability, public and private property and personal privacy. It is precisely because of the existence of network information security problems that a large number of network Important data stored and transmitted in the network needs to be effectively protected. [0003] In order to ensure the security of special data or industry data, network data needs to be transmitted in an e...
