Physical unclonable function device
Webb12 apr. 2024 · A PUF is a physical structure from which a device-unique and unclonable cryptographic key is created. It leverages the deep-submicron variations that occur naturally during the chip-manufacturing process and gives each transistor slightly random electrical properties. There are different ways to use a PUF to secure a device. WebbQuestion 1. (25 pts) Recall the concept of Physically Unclonable Functions, which are an important component of hardware based security. Here is a simple scenario and simple protocol using PUFs for authenticating a tag (and the device or tag holder they should uniquely identify). In the protocol below, the Reader stores ALL possible ...

WebbTherefore, the physically secure authentication and key agreement (AKA) protocol is urgently needed for IoV to implement access control and information protection. In this paper, physical unclonable function (PUF) is introduced in the AKA protocol to ensure that the system is secure even if the user devices or sensors are compromised. WebbIndex Terms—physically unclonable function, machine learn-ing, entity authentication. I. INTRODUCTION S INCE their advent in the early 2000s [1], [2], physically unclonable functions (PUFs) have been used as a building block in numerous authentication protocols. The authentication is either unilateral, i.e., one-way, or mutual, i.e., two-way, and
