Abstract

The invention designs a high-performance superscalar elliptic curve cryptographic processor chip shown as in the figure and relates to the technical fields of information security, encryption and decryption and chips. The chip designed by the invnetion adopts the modern processor superscalar technology,fully utilizes an instruction set to double the operational performance; a high-speed finite field multiplier greatly improves the computational efficiency, and properly solves the performance bottleneck of an elliptic curve cryptographic processor; the instruction set including the finite field arithmetic operation supported by the processor not only ensures that an elliptical curve cryptographic algorithm is more convenient to realize, but also makes necessary preparation for the future standardization; and the chip has a wide application prospect in the fields requiring information security, such as finance, communication and national defense.

Description

technical field [0001] The invention relates to the fields of information security, encryption and decryption technology, and chip technology, in particular to a high-performance elliptic curve cryptographic processor chip. Background technique [0002] As the most widely used in the world today, it is also the first real public key cryptosystem, RSA is based on the difficult problem of large number decomposition, with simple mathematical principles (mainly relying on Fermat's little theorem, and P does not Equal to the assumption of NP), the advantage of being relatively easy to realize, but its unit security strength is low, and the amount of calculation for encryption and decryption is too large. The elliptic curve public key cryptosystem, as an in-depth research issue in the academic circles in recent years, has been increasingly recognized and respected by the industry. It has high unit security strength (160-bit elliptic curve key has the same security), relatively le...

Problems solved by technology

[0003] However, the application of elliptic curve cryptography currently faces the following problems. The first is performance: most elliptic curve cryptography is implemented using software or single-chip microcomputers. The performance of these two methods is too low to meet high-performance encryption and decryption. requirements, and there has not yet been a widely used elliptic curve cryptographic processor chip implemented in the form of an ASIC; secondly, in the realization of the elliptic curve cryptosystem, the low performance of the finite field multiplication component has always been a bottleneck, and the finite field multiplication operation The low performance of elliptic curve cryptographic chips seriously restricts the wide application of elliptic curve cryptographic chips; finally, the special elliptic curve cryptographic instruction set has not yet appeared, and both general-purpose processors and special-purpose processors do not support finite-field arithmetic operations, and there is an urgent need for a finite-field arithmetic The instruction set standard of operation, which also greatly promotes the wide application of elliptic curve public key cryptosystem
