The dynamic surge of IOT-based smart infrastructure (smart grids, smart healthcare systems and industrial IOT) have introduced new opportunities and threats never faced before. The high computational, memory and energy requirements make conventional crypto-graphic solutions inappropriate on a resource constrained devices despite their great security. This paper outlines the design and analysis of a light cryptographic protocol that relies on Elliptic Curve Cryptography(ECC) in order to safely exchange keys, PRESENT algorithm in order to securely encrypt and SPONGENT algorithm in order to verify integrity.
