Executive Summary

So far the present authors have made an intensive study of using as few trapdoors as possible in the secret sequence based on a probabilistic encryption. In this paper, by following this paper, they present a probabilistic differential knapsack PKC with no trapdoor in the secret sequence. They also discuss on the security of the proposed scheme and show that the proposed scheme is secure against the low-density attack and the attack of disclosing secret key.
