Secure Elliptic Curve Cryptography based RFID Authentication Schemes for Internet of Things

摘要

In medical field, patients generally need highly equipped systems because of their inability to access emergency systems. In such situation, high level of security must be ensured to prevent fatal medical errors. RFID technology is generally used in the medical environment. Applications of elliptic curve algorithm are considered and several cryptography modules are analyzed. Heavy weight schemes are considered to be highly secure. Security drawbacks have been analyzed in Godor and Imre scheme in terms of maximum delay and running time and improved encryption and decryption scheme has been proposed. The proposed algorithm has been simulated in Xilinx 14.5 ISE and worst case slack, running time and frequency has been analyzed.
