FPGA-BASED KEY NEGOTIATION METHOD AND DEVICE

摘要

One or more embodiments of the present description provide an FPGA-based key negotiation method and device. Said method may comprise: an FPGA structure loading a deployed circuit logic configuration file onto an FPGA chip, so as to form a key negotiation module on the FPGA chip; the FPGA structure performing remote key negotiation with a client by means of the key negotiation module, so as to obtain a configuration file deployment key at the FPGA structure and the client respectively; the FPGA structure decrypting an encrypted new-version circuit logic configuration file from the client on the basis of the configuration file deployment key, and updating the deployed circuit logic configuration file on the basis of the obtained new-version circuit logic configuration file, so that the FPGA structure is implemented as a trusted execution environment on a block chain node to which the FPGA structure belongs.
