Proposed Method for Text Encryption Using Two Secret Keys and One Secret Mathematical Equation

Abstract

Information security is a vital issue and it needs to continuous developments. This paper focused on developing the concept of encryption by using a proposed method to encrypt text information or may be after some farther processing it is suitable for all types of files. This method used two secret keys (symmetric encryption) and one secret mathematical equation, and there are two levels of encryption; firstly through first secret key (key1) (convolution key); secondly through another secret key (key2) and secret mathematical equation. The cipher text is only real numbers. Also this paper will include some results of encryption and decryption.
