How to fill out Knapsack Cryptosystems

1. Select a superincreasing sequence of positive integers.
2. Choose a modulus that is larger than the sum of the superincreasing sequence.
3. Generate a public key by choosing a random integer that is coprime to the modulus.
4. Compute the corresponding private key using the inverse of the public key modulo the modulus.
5. Encode the message as a subset of the superincreasing sequence.

What are the different strategies to solve knapsack problems?

In the 0/1 knapsack problem, we are not allowed to break items. Fractional knapsack problem, we can break items for maximizing the total value of the knapsack. 4. 0/1 knapsack problem, finds a most valuable subset item with a total value less than equal to weight.

What is the knapsack problem encryption?

The Knapsack Encryption Algorithm is an encryption technique that uses a public key based on the knapsack problem. It changes messages into unreadable data without the private key.

What is knapsack problem in English?

In the knapsack problem, you need to pack a set of items, with given values and sizes (such as weights or volumes), into a container with a maximum capacity . If the total size of the items exceeds the capacity, you can't pack them all.

What is the knapsack cryptosystem?

Knapsack cryptosystems are cryptosystems whose security is based on the hardness of solving the knapsack problem. They remain quite unpopular because simple versions of these algorithms have been broken for several decades.
