Description

technical field

[0001] This invention relates to electronic circuits and, in particular, to radix-16 high speed Montgomery modular multipliers very large scale integration (VLSI). Background technique

[0002] At present, the rapid development of the Internet makes information security technology particularly important, such as online shopping, online banking, data downloading, etc., all need an identity authentication system. In modern cryptography, public key cryptosystem is used to accomplish this task, which can provide a series of security guarantees such as digital signature, identity authentication, data integrity and non-repudiation.

[0003] In the public key cryptosystem, the most widely used is the RSA cryptographic algorithm (RSA cryptographic algorithm is an asymmetric cryptographic algorithm). The RSA encryption algorithm is simple and effective, but it is very time-consuming, because the basic operation of RSA is exponentiation operation, and its operand leng...
