Zu Chong's encryption algorithm acceleration method, system, storage medium and computer equipment

Abstract

The invention relates to the technical field of information security, and specifically discloses a Zu Chongzhi encryption algorithm speed-up method. The method includes: based on a multi-channel cache ring mode, the key initialization of the Zu Chongzhi encryption algorithm and the plaintext logic operation process are executed in parallel in multiple channels. Based on the multi-channel cache ring mode, the invention runs Zu Chongzhi's algorithm separately, so that the logic of Zu Chongzhi's algorithm is separated, and the key initialization and plaintext logic operation are executed in parallel in multiple channels, which improves the data encryption operation ability and reduces the delay of real-time business application. The invention also discloses a Zu Chong's encryption algorithm speed-up system, storage medium and computer equipment.

Description

technical field

[0001] The invention relates to the technical field of information security, and in particular, to a method, system, storage medium and computer equipment for speeding up an encryption algorithm of Zu Chong. Background technique

[0002] The Zu Chongzhi algorithm set (ZUC algorithm) was developed by the Data Protection and Communication Security Research Center (DACAS) of the Chinese Academy of Sciences, 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 of wireless mobile Communication system (LTE) international standard.

[0003] Zu Chongzhi's encryption algorithm 128-EEA3 is a word-oriented stream cipher. It takes an initial key of 128 bits as input and an initial vector (IV) of 128 bits, and outputs a keystream of words (thus every 32 bits is called a key word). The keystream can be used to encrypt / decrypt information.
