Key agreement method and device based on fpga

Abstract

One or more embodiments of this specification provide an FPGA-based key agreement method and device, the method may include: the FPGA structure loads the deployed circuit logic configuration file onto the FPGA chip to form a key agreement on the FPGA chip. A key agreement module; the FPGA structure carries out remote key agreement with the client through the key agreement module, so as to obtain configuration file deployment keys at the FPGA structure and the client respectively; the FPGA structure is based on The configuration file deployment key decrypts the encrypted new version of the circuit logic configuration file from the client, and updates the deployed circuit logic configuration file based on the obtained new version of the circuit logic configuration file, so that the FPGA structure realizes It is the trusted execution environment on the blockchain node to which it belongs.

Description

technical field [0001] One or more embodiments of this specification relate to the field of blockchain technology, and in particular to an FPGA-based key agreement method and device. Background technique [0002] Blockchain technology is built on top of transmission networks such as peer-to-peer networks. Network nodes in the transmission network use chained data structures to verify and store data, and use distributed node consensus algorithms to generate and update data. [0003] At present, the two biggest challenges in the technology of enterprise-level blockchain platforms are privacy and performance, and it is often difficult to solve these two challenges at the same time. Most solutions trade for privacy by losing performance, or pursue performance with little regard for privacy. Common encryption technologies to solve privacy problems, such as Homomorphic encryption and zero-knowledge proof, are highly complex, poor in versatility, and may cause serious performance...
