Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] like figure 1 Shown is a schematic structural diagram of an embodiment of an encryption card provided by the present invention, consisting of figure 1 It can be seen that the encryption card includes an encryption chip, a DSP processor, an interface control circuit and a PCI interface circuit. The number of DSP processors, interface control circuits and encryption chips is equal but not limited, at least two, one DSP processor independently controls one encryption chip, and the corresponding DSP processor and encryption chip are connected through a corresponding interface control circuit For communication, the DSP processor receives data packets from the driver, and sends them to the encryption chip for processing through the interface control circuit. The DSP processor is connected with a PCI interface circuit, and the PCI interface circuit is a channel for r...

Abstract

The invention provides an encryption and a decryption method for an encrypt card. The encrypt card comprises encryption chips, DSP (digital signal sensor) processors, interface control circuits and a PCI (programmable communication interface) circuit; the number of the DSP processors, the number of the interface control circuits and the number of the encryption chips are equal and are at least two, one DSP processor controls and is connected with one encryption chip by one corresponding interface control circuit; and at least two DSP processors are connected with the PCI circuit to achieve the data transmission of the encrypt card between computers. A non-preemption interruption mutual exclusion mechanism is adopted to avoid interruption emption based on interruption priority, reduce the phenomenon of packet loss and guarantee the correctness and order of the data packet processing procedure.

Description

technical field [0001] The invention relates to the field of electronic information security, in particular to an encryption and decryption method for an encryption card. Background technique [0002] With the rapid development and wide application of information and network technology, business data in pillar industries such as banking, petroleum, and electric power have been widely used in various computer equipment for communication. Due to the importance and particularity of the industry, data encryption security must be considered Transmission, therefore, the development of server equipment for encryption processing has been widely carried out in the industry. The server equipment can change the data from plaintext to encrypted data, and then the data is transmitted to the destination by the network equipment. The mainstream encryption server in the information security industry In the equipment, the main task of data encryption is the PCI interface encryption card inte...
