The study on the circuit architecture of reconfigurable physics-based unclonable technology
Baigen He, Gang-gang Qiu · 2025
With the rapid development of computer technology and internet technology, the issue of information security has become increasingly prominent. Physical Unclonable Technology (PUT), based on circuit implementation, is a highsecurity technology that differs from traditional cryptography in that it employs logic gates with variable quantities and distinct gate circuits. PUT can be applied in various fields such as authentication, secure encryption, cryptographic computation, and more. Compared to traditional cryptography, PUT offers advantages including high security, strong resistance to attacks, and flexible operation, which has led to its widespread application in the field of information security. Information security refers to the protection and maintenance of information resources from unauthorized or inappropriate access, use, modification, and other potential hazards. It is a product of the information age, encompassing any actions or events that may cause or potentially cause damage to information resources. Traditional cryptography has some drawbacks in ensuring data security, such as the ease of device loss, inconvenient key storage, and difficulties in decryption. Therefore, the development of new cryptographic technologies is necessary to address these issues.
