Problems solved by technology

[0010] Since the encryption algorithm and hash algorithm implemented in the device have been determined, the device using this scheme can only meet the needs of limited scenarios, and lacks adaptability to other and future encryption algorithms and hash algorithms. If it is necessary to support new encryption algorithm or hash algorithm, it is necessary to redesign the chip and tape out, which requires a lot of cost

Embodiment 1

[0048] Will figure 2 If the algorithm processing module in is set as an algorithm interface module, then the newly generated security processing system is composed of a security processing device and at least one auxiliary security processing device. Specific as image 3 As shown, wherein, the auxiliary security processing device is composed of an algorithm interface module, an encryption algorithm module and / or a hash algorithm module, and the algorithm interface module is used to complete the transfer of data packets between the security processing device and the auxiliary security processing device; the encryption algorithm module and / or the hash algorithm module is used to perform algorithm processing on the data packet. .

[0049] When the security processing system performs protocol decapsulation, the data packet is transmitted to the protocol processing module through the data interface module for protocol decapsulation. Then the protocol processing module judges a...

Embodiment 2

[0055] Set the algorithm processing module added in the security processing device as a programmable algorithm module, such as Figure 5 As shown, the programmable algorithm module is readable and writable. On this module, the encryption algorithm or hash algorithm that the device does not have originally is programmed. Through the selective call of these algorithms by the protocol processing module, the flexibility of the original algorithm is realized. Replenish.

[0056] First program one or more encryption algorithms and / or hash algorithms in the programmable algorithm module, and the data packet is transmitted to the protocol processing module through the data interface module for protocol decapsulation. The protocol processing module judges the encryption algorithm required by the data packet When included in the encryption algorithm module 1 in the security processing device, the data packet is sent to this module for processing, and after encryption or decryption, the ...

Description

technical field [0001] The present invention relates to the fields of electronics, communication and computer, in particular to a data security processing method, device and system. Background technique [0002] In recent years, people pay more and more attention to network security issues. Since the Internet and most packet switching networks are built on the Internet Protocol (IP), to solve the security problems of these networks, the security issues of the Internet Protocol must be solved first. Protocols that address Internet Protocol communications security include: [0003] IPSec: Internet Protocol Security, Internet Protocol Security; [0004] SSL: Security Socket Layer, Secure Socket Layer (protocol); [0005] TLS: Transport Layer Security, Transport Layer Security (protocol), etc., which use encryption algorithms and hash algorithms to protect the confidentiality and integrity of Internet protocol communications. [0006] The current security processing device st...
