Intelligent Secure System

Artificial intelligent is the science and study how the computer can perform the activities that the human bring can do. The outputs of AI system are either reports or actions, these outputs depend on the information and knowledge that are stored in the computer which represent the problem that the system wants to solve it. The Artificial Intelligent is used in the cryptography in many application such as cryptanalysis of some kind of ciphering methods for example the cryptanalyzing of the convention cipher systems the simple substation cipher systems depend on the cipher text only attack. In this research we construct the encryption and decryption algorithms depending on the artificial intelligent concept such that computational Linguistics. These algorithms convert the original (plaintext) message to ciphertext message by generation natural language. Thats mean, the ciphertext message stay natural language also. We constructed four algorithm depending on the degree of security, each one presented kind of security by selecting the method to generating the text. These algorithm gives good randomness and be able to hide the properties of natural language, by using inner keys. These keys changed dynamically during text generation to produced ciphertext. These algorithms gives the safety to ciphertext from attack, thats because, the output text is natural and prevent the intruder curiosity to cryptanalysis ciphertext. In addition to these algorithm (except first one, base text generation algorithm) roubest against the statistical cryptanalysis.
