FPGA-based multi-algorithm security encryption authentication system and method

Abstract

The invention belongs to the technical field of data encryption authentication, and discloses an FPGA-based multi-algorithm security encryption authentication system and method. The FPGA-based multi-algorithm security encryption authentication system comprises: an FPGA terminal, i.e., an encryption authentication chip, used for encryption authentication; a transmission module used for transmittinginstructions and data through a serial port protocol; and a host end used for configuring and verifying the encryption authentication chip. According to the security encryption authentication system,multiple different encryption algorithms can be selected during identity authentication, and compared with a single algorithm authentication system, the security encryption authentication system hasthe advantages that the cracking difficulty is increased, and the security coefficient is improved. According to the invention, the RO PUF is constructed by utilizing random difference generated during manufacturing of an integrated circuit to generate a chip key, so that the chip key cannot be re-etched, and is safer than a key stored in a nonvolatile memory. According to the method, the value ofeach bit of the PUF is generated and compared for many times to confirm the final value, so that the stability of the PUF value is improved.

Description

technical field [0001] The invention belongs to the technical field of encryption authentication, in particular to an FPGA-based multi-algorithm security encryption authentication system and authentication method. Background technique [0002] At present, the closest existing technology: In recent years, with the rapid development of the Internet and blockchain technology, and the widespread use of mobile terminal equipment, people are paying more and more attention to network security and information security issues. As the first gateway to protect network resources, identity authentication is of great significance to the security protection of information systems. However, identity authentication systems, especially cryptographic chips, often become the target of attacks, and attack methods and methods emerge in endlessly. Traditional encryption and authentication chips use non-volatile memory devices to store keys, and the stored content can be read out through physical ...

AI Technical Summary

Problems solved by technology

[0061] To sum up, the problems existing in the existing technology are: the traditional encryption chip uses non-volatile memory to store the key, which is easy to be attacked to read important data; the encryption algorithm of the traditional encryption chip is single, and the selectivity is not high; the structure of the traditional encryption chip It is more complicated and requires more parameters to be configured

Using structures such as fuses, if the output is logic 0 before programming, the output will be logic 1 after programming, and cannot be changed to 0
