Encryption starting device and method of FPGA product and related components

Abstract

The invention discloses an encryption starting device, method and equipment of an FPGA product and a readable storage medium. The encryption starting device comprises a calculation module, an OTP programming module, an OTP, a verification module and a starting module. When the FPGA product is produced, the calculation module obtains a logic data bit stream of a target version and performs encryption calculation to obtain a first abstract value, and the verification module verifies the logic data bit stream to obtain a second abstract value; the OTP programming module writes the first abstractvalue into OTP; when the FPGA product is applied, the calculation module carries out encryption calculation on the current logic data bit stream in the FLASH to obtain a second abstract value, the verification module judges whether a first abstract value identical to the second abstract value exists in the OTP or not, and if yes, the starting module is triggered to start the FPGA product. According to the method and the device, the version of the logic data bit stream in the FLASH is correct, safe and complete, and logic data bit stream errors caused by informal versions of logic data bit streams and misoperation or security vulnerabilities can be effectively avoided.

Description

technical field [0001] The invention relates to the field of hardware security, in particular to an encryption startup device, method and related components of FPGA products. Background technique [0002] At present, in the development process of FPGA (Field Programmable Gate Array, Field Programmable Logic Gate Array) products, it is necessary to repeatedly program the logic data bit stream of the FPGA device. There is no need to control it, but after the project is completed, the logical data bit stream provided to the customer needs to be well versioned and security managed. [0003] The existing technical solution can encrypt the logical data bit stream by software through the encryption and decryption algorithm, and then transmit it into the FPGA device, and call the decryption module inside the FPGA to decrypt the logical data bit stream. After successful decryption, the logical data bit stream can be decrypted start up. This method cannot manage the logical data bit...
