A Trapdoor Multiple Mapping

Research output: Contribution to journalArticlepeer-review

3 Scopus citations


A public key cryptosystem is suggested in which a message is enciphered by adding its numerical value to a sum of elements selected randomly from a publicly known knapsack, thus enabling multiple mapping of the message. Data expansion is moderate while reasonable security is maintained. Since the selected knapsack elements are message-independent, the encryption is very fast.
