Mathematical Model for Classical Cryptography

Dr. Mahdi F. Mosa

In this article we present a mathematical model for classical encryption of a plain text for secure confidential information through unsecure channel. The method of encryption based on the generation of prime numbers, seventh order number system and mathematical theory of matrices. We form the matrix A for the plain text, for simplicity of calculation. The result shows that this model provides an acceptable secure exchange of information within a close circle net of a company and it can be on wider than that. The 7 system is a system with seven numbers namely (0,1,2,3,4,5,6) with radix 7 and we can change any decimal number or other system number to the 7 system. The receiver has the password and the process of encryption to decrypt the message. Also we notice that this model can be wider through bilingual and other system of numbers.
