Elliptic curve cryptosystem provides greater security for any key size, when compared to integer factorization and discrete logarithm system. Generally in digital signature scheme, signature (r, s) along with message will be sent to the receiver but in this approach, signature alone is sent and message will be recovered from signature. This project deals with implementation of knapsack based Elliptic Curve Cryptography (ECC) for digital signature authentication with message recovery. The strength of knapsack algorithm depends on the selection of the knapsack series. Stern series which reduces...
