Problems solved by technology

Since the PBKDF2 algorithm has a pseudo-random function HMAC-SHA-1 with a large number of iterations, the CPU usage and space overhead of the HMAC-SHA-1 algorithm increase accordingly, so the overall algorithm execution speed will be dragged down

Abstract

The invention discloses an optimization acceleration method and device for a PBKDF2 cryptographic algorithm, equipment and a storage medium. Comparing with traditional techniques, 16 32-bit words of the block processed by the HMAC-SHA-1 encryption algorithm are expanded into 80 32-bit words on the basis of an Intel optimization algorithm, according to the HMAC-SHA-1 encryption algorithm, under thecondition that a plurality of ALU assembly lines are adopted, a single instruction and multiple data streams can be fully utilized; therefore, the memory overhead and the occupation of the CPU can begreatly reduced; the operation speed of the HMAC-SHA-1 encryption algorithm is improved, and the operation speed of the PBKDF2 algorithm can be correspondingly improved by optimizing the operation speed of the HMAC-SHA-1 encryption algorithm due to the fact that the PBKDF2 algorithm has the pseudorandom function HMAC-SHA-1 with the large number of iterations. Therefore, the space overhead and theCPU usage amount of the HMAC-SHA-1 algorithm can be reduced, and the optimization of the HMAC-SHA-1 algorithm is realized, so that the operation speed of the PBKDF2 cryptographic algorithm is improved.

Description

technical field [0001] The invention relates to the technical field of encryption, in particular to an optimization acceleration method, device, equipment and storage medium of the PBKDF2 encryption algorithm. Background technique [0002] In today's world filled with all kinds of information, protecting sensitive data and information that is stored, transmitted or shared has become a very important topic. Using passwords is a very common and simple way to keep user information safe. The correct use of passwords to protect sensitive data and information requires not only choosing strong passwords, but also choosing a secure method to handle passwords in software and hardware systems, so a variety of encryption algorithms have been produced, and with the increase in computing power Constantly improving, the types of encryption algorithms are constantly being updated, and the strength is also constantly improving. The computing core of most cryptographic algorithms includes ...
