A Systematic Encryption Algorithm for Knapsack Scheme Using Random Sequence
Shinsuke Hamasho, Yasuyuki Murakami, Masao Kasahara · Journal of Communications and Information Sciences · 2013
Authors, formerly, proposed a new knapsack cryptosystem which uses a random sequence as its secret key. In this paper we first propose a systematic encryption algorithm for this cryptosystem. We then evaluate the amount of information of plaintext when using this algorithm. It is concluded that the proposed systematic encryption algorithm is sufficiently practical.
