A lightweight authentication system based on an improved dapuf circuit

Abstract

The invention discloses a lightweight authentication system based on an improved DAPUF circuit. The certification system is divided into registration stage and certification stage. In the registrationstage, the improved DAPUF is used to generate the stable unique ID as the authentication reference standard for the FPGA manufacturer, system developer, IP core manufacturer and end user. In the certification phase, the parts communicate with each other through the eigenvalue ID, the eigenvalue ID of the visitor is compared with the reference standard ID for preliminary authentication, and afterwards, the visitor obtains the final access rights licenses by controlling the state machine FSM embedded in the IP core through the PUF response embedded in the FPGA device, so as to realize the protection of the specific IP and product on the specific FPGA device. The invention has the advantages of low resource consumption, strong stability, strong anti-attack performance, high safety, simple realization and wide application range.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a lightweight authentication system based on an improved DAPUF circuit. Background technique [0002] RFID is gaining popularity in security applications such as access control and official documents. However, establishing reliable security engineering based on RFID is still an elusive problem due to the highly constrained nature of these devices. Lightweight protocols based on encrypted anti-counterfeiting make devices vulnerable to attackers. Therefore, various protocols using standard encryption functions have been proposed for RFID, however these protocols incur high costs in terms of implementation area. [0003] FPGA design has the advantages of short time to market, low cost and high flexibility. These make FPGAs a popular design platform for many applications such as automotive electronics, consumer electronics, and aerospace equipment. In FPG...
