Abstract

Internet-of-Things (IoT), an integral part of today’s smart society, is facing tremendous challenges of different security and interoperability attacks. Also, IoT device works in resource-constrained environments with limited storage. Conventional cryptography is not suitable for low-cost IoTs, and also they are susceptible to physical attacks. This work proposes a lightweight authentication and key exchange protocol utilizing the physically unclonable function (PUF) as security primitive. A single PUF challenge-response pair (PUF-CRP) is utilised to overcomes the server’s storage overhead in the proposed protocol. Also, this protocol ensures the secret message passing using the lightweight XOR function. The proposed protocol authenticates the end-user successfully as well as maintains the security of the shared secret. The two-pass approach of the proposed method builds confidence in communicating entities. Formal analysis by automated Proverif tool validates its security. Performance evaluation advocates the superiority of the proposed protocol over the existing methods upholding its strong security and lightweight feature.
