2020-020 – New PUF-based Protocol for Improved Data Security and Authentication

Researchers from Kansas StateUniversity have developed an improved PUF-based protocol known as the reliableand lightweight authentication protocol (PUF-RLA). The proposed schememakes the system more reliable against errors and adversarial attacks, usingthe following features: Obfuscation of identity (Challenge-Response Pairs or CRPs) of the devices. The adversary cannot obtain CRPs by utilizing passive or active attacks, and hence no model could be generated for any device. Unlike most previous approaches, this PUF circuit is not directly accessible. This prevents the device from side channel analysis attacks, as well as machine learning attacks. The control logic keeps the PUF secure from brute force and modelling attacks. The response accuracy is also expected to be superior to previous approaches as the server contains the error correction codes (helper data). Aarushi Gupta-Sheth aarushi@ksu.edu 785-532-3907
