摘要
En 中文
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.
