SIMPLE ENCRYPTION ALGORITHM USING MATHEMATICAL COMPLEMENT

The role of mathematics in all fields of science is very clear; one of these areas is data security. In this paper, a method of coding data based on a simple mathematical process is proposed. This method depends on the use of the complementary number, which represents the key. The encrypted message, which is a series of numbers, is sent via the transmitter channel, the recipient of the encrypted message extract the explicit text from the encrypted message using the value of the complement. This method has been tested using many testing tools like decimalization attack, M-138 attack, factorization attack. The results show the strength of the proposed encryption algorithm.
