WebThe existing system uses only Merkle-Hellman Knapsack Cryptosystem and CBC Mode to encrypt the messages and decrypt them in reverse order. In Figure 1, The existing system shows the encryption process with two techniques, CBC and Merkle-Hellman and in Figure 2, the decryption process is shown.

WebMerkle-Hellman Knapsack Cryptosystem. This well-known cryptosystem was first described by Merkle and Hellman in 1978. Although this system, and several variants of it, were broken in the early 1980's, it is still worth studying for several reasons, not the least of which is the elegance of its underlying mathematics.
