Secured elliptic curve cryptosystems for scan based VLSI architecture

Ellipti curve Cryptosystem used in cryptograhy chips undergoes side channel threats, where the attackers deciphered the secret key from the scan path through finding the memory element position by applying reverse enginering process in montgomery algorithm used in Elliptic device. Hence we propose the modified scan path architecture through the addition of extra electronic componet inorder to protect the secret key against the threats. The modified elliptic curve crypro scan architecture written in verilog code and simulated using model Sim Tool. The hardware module core is synthesised using Xillinx Spartan III Field Programable Gatted Array (FPGA) kit. The perfomance utilization is reported with the help of generated synsthesis result.
