The quest of modern cryptography is to prove the security of cryptographic systems mathematically. The most well known procedure for this is to base the design of cryptographic algorithms on problems that have a high level of computational complexity. In this paper we describe a single-key encryption scheme and offers a proof of the computational complexity of this scheme based on the NP-complete Clause Satisfiability Problem (CSP).
