Embodiment Construction

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0037] figure 1 The flow chart of Zu Chong's encryption algorithm speed-up method provided by the embodiment of the present invention. Such as figure 1 As shown, the method includes:

[0038] Based on the multi-channel cache ring mode, the key initialization and plaintext logic operation process of Zu Chongzhi's encryption algorithm are decoupled, and multi-channel parallel execution is performed.

[0039] In the above-mentioned embodiment, based on the multi-channel cache ring mode, Zu Chong’s algorithm is operated separately, so that the logic of Zu Chong’s algorithm is separated, and the key initialization and plaintext logic operations are executed in parallel in multiple channels, which improves the data encr...

Abstract

The invention relates to the technical field of information safety, and particularly discloses a Zu-Chongzhi encryption algorithm acceleration method. The method comprises the step of performing secret key initialization and plaintext logic operation process multichannel parallel execution of an ancestral encryption algorithm based on a multichannel cache ring mode. Based on a multi-channel cachering mode, an ancestral algorithm is operated separately, so that logic separation of the ancestral algorithm. The key initialization and plaintext logic operation are executed in parallel in multiplechannels. The data encryption operation capability is improved. The real-time service application delay is reduced. The invention further discloses a Zu-Chongzhi encryption algorithm acceleration system, a storage medium and computer equipment.

Description

technical field [0001] The present invention relates to the technical field of information security, in particular to a method, system, storage medium and computer equipment for speeding up encryption algorithms of Zu Chong. Background technique [0002] Zu Chongzhi Algorithm Collection (ZUC Algorithm) was developed by the Data Protection and Communication Security Research Center of the Chinese Academy of Sciences (DACAS), including Zu Chongzhi Algorithm, Zu Chongzhi Encryption Algorithm 128-EEA3 and Zu Chongzhi Integrity Algorithm 128-EIA3, which have been included in the 3GPP new generation wireless mobile Telecommunications system (LTE) international standard. [0003] Zu Chongzhi's encryption algorithm 128-EEA3 is a word-oriented stream cipher. It takes a 128-bit initial key as input and a 128-bit initialization vector (IV), and outputs a key stream in terms of words (thus every 32 bits is called a key word). Keystream can be used to encrypt / decrypt information. [0...
