Sponge based lightweight authentication mechanism for RFID tags

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.
