Abstract

The embodiment of the invention discloses an asymmetric algorithm calculation circuit, which is characterized in that an asymmetric algorithm is divided into a plurality of calculation levels according to a priority sequence of calculation symbols in a corresponding calculation formula, and each calculation level adopts a calculation module for calculation. The connection mode of the calculation units in each calculation module corresponds to the data transmission relation in the corresponding calculation level, and the connection relation between the calculation modules corresponds to the data transmission relation between the corresponding calculation levels. According to the embodiment of the invention, through mutual cooperation of the calculation modules, parallel calculation of a plurality of calculation formulas in the asymmetric algorithm can be realized, the operation speed and the operation efficiency of the asymmetric algorithm are improved, and the technical problem that the operation speed is relatively low when the calculation of the asymmetric algorithm is carried out in the prior art is solved.

Description

technical field [0001] The embodiments of the present application relate to the field of digital IC circuit design, and in particular to an asymmetric algorithm calculation circuit. Background technique [0002] At present, elliptic curve encryption algorithms are usually used in asymmetric cryptographic chips. The public key cryptography of elliptic curves is composed of point multiplication, point doubling, point addition and modular exponentiation operations during curve calculation. The public key cryptography can finally be decomposed into Modular multiplication, modular addition, and modular subtraction operations; among them, modular addition and modular subtraction are less difficult and require less computation time, while modular multiplication is more difficult and results in longer computation time. [0003] In the prior art, the realization of dot multiplication calculation is mainly to decompose the dot multiplication into dot addition and double dot calculatio...
