Embodiment Construction

[0040] A low-overhead design method for a hybrid configurable RO PUF utilizing a cross-path selection structure, comprising the following steps:

[0041] Step 1): Initialize settings

[0042] The initialization settings include the setting of the number of bits of the physical unclonable function and the setting of the physical unclonable unit.

[0043] Wherein, the setting of the number of bits of the physical unclonable function is preset in the FPGA through the design file, and in the present invention, the number of bits of the physical unclonable function is set to 512 bits.

[0044] And the position of the physical unclonable function generation unit on the FPGA is defined by the preset of the constraint file. In this embodiment, four physical unclonable function generation units are implemented on the FPGA;

[0045] In the present invention, each physical unclonable function generation unit includes two groups of ring oscillator pairs, each group of ring oscillator pai...

Abstract

The invention discloses a low-overhead design method of a hybrid configurable RO PUF using a cross-path selection structure. The present invention includes the following steps: 1): initialize setting; set the number of bits of the physical unclonable function and the position of the physical unclonable function generation unit on the FPGA, and implement several physical unclonable function generation units on the FPGA; 2) : Excitation configuration; input excitations C1 and C2 respectively configure the configurable inverter and cross-path selection structure in the physical unclonable function generation unit; 3): PUF generation; two in each physical unclonable function generation unit The group ring oscillator is centered, and the upper and upper channels are counted and compared, and the lower and lower channels are counted and compared to ensure a high degree of symmetry. The present invention increases the PUF response bit through the cooperative use of the configurable inverter and the cross-path selection structure, thereby realizing the purpose of reducing the hardware overhead.

Description

technical field [0001] The invention belongs to the technical field of information security and integrated circuits, and in particular relates to a low-overhead design method of a hybrid configurable RO PUF using a cross-path selection structure. Background technique [0002] With the rapid development of electronic information technology, information communication between devices is becoming more and more relevant, and information security issues are getting more and more attention. Traditional encryption methods are usually authenticated and encrypted based on keys, but keys are generally stored in non-volatile memory and are vulnerable to intrusive and non-intrusive attacks, resulting in key leakage and failure of system protection mechanisms. In order to effectively solve the above security problems, Physical Unclonable Function (PUF) came into being. PUF transcends the limitations of traditional security key storage methods, and can solve the problems existing in tradi...
