Design and Implementation of Synthesizable Two-Level Cryptosystem for High-Security enabled Applications

With a greater reliance on digital data in the most recent technological era, maintaining its security is also a crucial task. The power of information in this day and age can be abused to commit immoral acts. Data must therefore be kept secure. In order to achieve double encryption, we have updated the Elliptic Curve Cryptographic (ECC) and Diffe-Hellman (DH) algorithms in this study. ECC is preferred primarily because it offers higher security with reduced key sizes. It uses left to right point multiplication, which requires less computing time than conventional techniques. The suggested changes result in a cypher text transmission that is half as large, resulting in an increase in transmission speed and a halving of memory consumption. As a result, when compared to a conventional ECC, we have improved security while also reducing computation time.
