RAS accelerator

Abstract

Provided is an RAS accelerator. The RAS accelerator comprises a control / state register, a data storage and an arithmetical logic unit, wherein the control / state register is connected with a system bus through a control line, the data storage is connected with the system bus through a control line and a data line, and the arithmetical logic unit is connected with the data storage through a data line. The RSA accelerator further comprises a complex function control module and a basic function control module. The control / state register is connected with the complex function control module and the basic function control module through control lines, the complex function control module is connected with the basic function control module through a control signal line, and the basic function control module is connected with the arithmetical logic unit and the data storage through control lines. A chip main central processing unit (CPU) summarizes and reads a final arithmetic result in the data storage through a system. The RAS accelerator has the advantages of being capable of improving arithmetic speed of an RAS algorithm and good in safety performance.

Description

technical field [0001] The invention relates to the field of public key encryption, in particular to an RSA accelerator. Background technique [0002] The RSA public key encryption algorithm was developed in 1977 by Ron Rivest, Adi Shamirh and Len Adleman (MIT, USA). RSA takes its name from the names of the three who developed them. RSA is currently the most influential public key encryption algorithm, it can resist all known cryptographic attacks so far, and has been recommended by ISO as a public key data encryption standard. The RSA algorithm is based on a very simple number theory fact: it is very easy to multiply two large prime numbers, but it is extremely difficult to factorize the product at that time, so the product can be made public as an encryption key. [0003] RSA is an asymmetric encryption standard. Its security comes from the difficulty of factorizing extremely large integers. Its encryption strength depends on the key length, that is, the larger the key l...
