Elliptic curve cipher processor

Abstract

The invention discloses an elliptic curve cipher processor, and relates to the field of information technology security and micro-processor design. The processor is of a transport triggered architecture (TTA) structure, and the hybrid flow mechanism of the elliptic curve cipher processor comprises a transmission flow and a functional unit flow. The elliptic curve cipher processor comprises a command memory, a fetch unit, a decoding unit, a register file, a bus internetwork, a Socket and a functional unit, wherein the fetch unit fetches a command in the command memory; the command is decoded by the decoding unit; the decoded command is subjected to an error correction code (ECC) operation by selecting a corresponding functional unit through the bus internetwork; operation data required by the functional unit is acquired through the register file or the functional unit; and the functional unit is interconnected with the Socket through the bus internetwork. By utilizing the elliptic curve cipher processor, the operation speedup ratio is improved, the engineering change cycle is shortened, a software and hardware collaborative design is realized, and the problem of going against secondary development is solved.

Description

technical field [0001] The invention relates to the fields of information technology security and microprocessor design, in particular to an elliptic curve cryptographic processor. Background technique [0002] With the continuous development and application of information technology, the issue of information security becomes more and more important. As the core of information security, cryptography plays an extremely important role in it. ECC (Elliptic Curve Cryptosystem, elliptic curve cryptosystem), as a public key cryptosystem, its security is based on the difficulty of finding ECDLP (Elliptic Curve Discrete Logarithm Problem, discrete logarithm problem on elliptic curve), which is widely used at present Compared with systems such as RSA and DSA, ECC has obvious advantages: the algorithm has high anti-attack strength, higher security, small amount of calculation, fast processing speed, short key length and required storage space than RSA or DSA. much smaller.
