CRYPTOSYSTEM BASED ON THE PRINCIPLES OF INDEFINITE INTEGRAL

Cryptography is one of the most important sciences used to protect the data transmitted over unsecure channel like the Internet. So, protecting data aims to hide the characteristics of the data from unauthorized parties. Therefore, there is a need for algorithms, which make the data difficult to break by unauthorized individuals. As a result, this research proposes the new encryption method to encrypt text by using the principle of indefinite integration, where the sender using the constant of the integral and the order of the equation to be integrating as two keys and the variable in the integration represent the character. The results show that the new cryptosystem is unbreakable through using many types of cryptanalysis attack.
