Sponge based lightweight authentication mechanism for RFID tags

Abstract

Lightweight authentication schemes suitable for resource constrained environments like IoT devices, sensor networks, Radio Frequency IDentification(RFID)tags, contactless smart cards etc., have gained a lot of attention in lightweight cryptographic community. Mostly hash funtions based on block ciphers are widely used for designing lightweight authentication schemes. However, in recent years designing such schemes from a hash function based on permutations using different modes is gaining lot of attention. They are efficient alternatives for the current block-cipher dominated cryptographic practices in pervasive device. We propose a new serverless sponge-permutation based lightweight authentication mechanism for proving RFID Tags authenticity to any legitimate reader and vice-versa.
