A Secured RFID Lightweight Authentication Protocol based on Elliptic Curve Cryptography using modified PRNG Algorithm

In this paper, the goal is to enhance the lightweight Authentication Protocol using Epoch Timestamp as Seed for PRNG Protocol based on Elliptic Curve Cryptography. The proposed enhancement uses PRNG Algorithm where randomness is generated using real-time system clock converted into running epoch timestamp as Seed for PRNG on LCG Algorithm that will do Bootstrap Iteration in generating a Random Number as keys for ECC Mutual Authentication Protocol. The result shows that the enhanced ECC Protocol utilizes smaller storage requirements of 2560bits + 640w bits, communication cost of 1,120bits faster response time and throughput, and lesser computational cost of 207ms for the Tag and the Server was achieved compared to Zheng Protocol. Also, the performance of this proposed Protocol has many advantages in terms of confidentiality, mutual authentication, availability, forward security, anonymity, spoofing/cloning, scalability and so on, which can resist tracking attacks, denial of service attacks, and system internal attack. It is therefore suggested that some practical applications using a RFID system that requires security for the lightweight authentication protocol should be introduced and more appropriate.
