Merkle–Hellman is a public key cryptosystem, meaning that two keys are used, a public key for encryption and a private key for decryption. It is based on the subset sum problem (a special case of the knapsack problem). The problem is as follows: given a set of integers and an integer , find a subset of which sums to . In general, this problem is known to be NP-complete. However, if is superincreasing, meaning that each element of the set is greater than the sum of all the number… WebDec 10, 2024 · The Knapsack encryption and decryption of these numbers are modeled using the Python program.
