A 256 bit implementation of ECC-RFID based system using Shamir secret sharing scheme and Keccak hash function

Abstract

The applications of using multi-tag RFID technology have rapidly grown to be used in different fields of life. However, security and privacy are the main issues with this technology. In RFID multi-tags applications, a number of tags need to be securely authenticated. Although, various authentication protocols have been proposed, most of these protocols still lack of providing enough security and privacy levels. In order to overcome the security and privacy issues, this paper discusses the implementation of high-performance 256 bit elliptical curve cryptography (ECC) based system with ElGamal threshold cryptosystem. The security and privacy levels are ensured by providing a 256 bit ECC with Shamir Secret sharing scheme to distribute secure information amongst multiple RFID tags. For ensuring integrity of the data, the Keccak hash function has been used in the authentication phases
