Knapsack Key-Generation System using Java']JavaScript on Web

Although some studies have been conducted in knapsack cryptosystems, it is not necessarily easy to generate keys in public-key cryptosystem. There are few open, scalability and easy to use systems. For web usage, programs written in Java Script have high transparency and scalability, and are very suitable for cryptosytems. This paper provides the necessary systems to generate keys, encrypt and decrypt in knapsack cryptosytem, which can be applied to most knapsack PKC by simply defining some functions including generating secret keys, translating into public keys and others. This paper also provides two examples, Merkle-Hellman and shifted odd knapsack PKC.
