Merkle–Hellman Knapsack cryptosystem. The Merkle–Hellman Knapsack cryptosystem was introduced in 1978 by Ralph Merkle and Martin Hellman. This cryptosystem has been proven to be insecure, however, as Adi Shamir published a successful attack on the Merkle-Hellman cryptosystem based on Shor's algorithm in 1984.

WebThe basic idea of knapsack is defined. We introduce the notion of a super-increasing set. WebIn a Merkle-Hellman cryptosystem, plaintext message units are of length 3 over the alphabet. The following sequence of ciphertext message units is received. and the secret key is b = 30966, m = 47107. Decrypt the message. Myself and a classmate are struggling to do this exam question so we would really appreciate some help!
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. WebRoughly at the same time when RSA was discovered [17], knapsack encryp- tion was introduced by Merkle and Hellman [ll]. It used the knapsack problem where P[easy] was superincreasing and shuffling was a linear operation modulo some large integer. As is well known, the knapsack cryptosystem was broken by Shamir.
