PUF-Based Authentication-Oriented Architecture for Identification Tags
IEEE Transactions on Dependable and Secure Computing(2024)
摘要
Smart tags are compact electronic devices affixed to or embedded into objects to facilitate identification, monitoring, and data exchange. Consequently, secure authentication of these tags is a crucial issue, as objects must reliably verify their identity before sharing sensitive information with other entities. The application of Physical Unclonable Functions (PUF) as a device's “digital fingerprint” has attracted significant attention, yet existing PUF-based authentication methods exhibit security vulnerabilities, either due to the authentication protocol itself or the limited reliability of the PUF technology used. Moreover, there has been a considerable focus on the software aspect, often overlooking the critical role of hardware design, which can become a target for attacks aimed at compromising the device's identity or act as a hindrance in the manufacturing process. In light of these points, this paper introduces an identification tag architecture that leverages PUF technology, focusing on authentication. This architecture features a straightforward but efficient authentication protocol, underpinned by a new and highly stable PUF model. The overall architecture encompasses particular hardware implementation aspects that significantly simplify the tag's enrollment phase and minimize vulnerabilities to attacks. The paper also describes a prototype of this identification tag and provide detailed insights into its application.
