Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0043] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0044] For the existing encryption protection method, only the logic code in the FPGA is protected, but the protection of the application program in the computer cannot be provided. The embodiment of the present invention is an information security system...

Abstract

The invention discloses an FPGA + processor architecture-based information security system and a working method thereof. The system comprises an FPGA, a general processor and a memory, wherein the FPGA is interconnected with a processor and a FLASH; the memory is used for power-on configuration of the FPGA and storage of software programs, and the stored software comprises an encryption bootstrapprogram and an encryption application program; the FPGA is used for decrypting the encrypted bootstrap program stored in the memory, and is also used for generating a ciphertext for decrypting and encrypting the application program by the processor through the encryption software running the application program key; and the processor is used for running the bootstrap program decrypted by the FPGAand running the decrypted application program. According to the embodiment of the invention, the problem that core data and key application program codes are easy to steal due to lack of information security confidentiality measures in the existing embedded computer is solved.

Description

technical field [0001] The present invention relates to but not limited to the technical field of embedded computer information security, especially an information security system based on FPGA+processor architecture and its working method. Background technique [0002] Cryptography technology is the leading force to ensure information security, and the research and application of cryptographic algorithms is the core research field of information security technology. Currently published national secret algorithms include: SM1 symmetric algorithm, SM2 asymmetric algorithm, SM3 hash (Hash) algorithm, SM4 block encryption algorithm. [0003] At present, some new FPGA chips integrate bit stream decryption logic to provide a high degree of design security. Without knowing the encryption key, would-be pirates cannot analyze the externally intercepted bitstream to understand or clone the design. For example, the 7 series FPGA produced by Xilinx can guarantee that the design canno...
