http://math.ucdenver.edu/~wcherowi/courses/m5410/ctcknap.html Webare known, several knapsack-type PKC‘s have been shown to be insecure. Most of those systems have a concealed “ superincreasing” sequence. Shamir made the first success- ful attack on the basic Merkle-Hellman system [29]. Fol- lowing his attack, other attacks against more complicated systems were proposed.

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.
