Secured cryptography by combination of One Time Pad encryption and Cipher Block Chaining Mode

In this paper we propose new methods for encryption by considering the theory of unbreakable one time pad cryptography. We show that how could we have a reliable method of encryption that in can be very simple in their implementers point of view and intensely complicated in attackers point of view. by optimizing the methods of generating random keys we made cipher texts highly secure and hardly to crack and unpredictable enough for any kind of cryptanalysis systems. in case of an appropriate implementation of one time pads specially by having a proper random key distribution we can make sure that secrecy and privacy of our data and communications in today’s complex and huge size of computer networks, would not be at risk of disclosure. We also combined the approaches of cipher block chaining mode and binary addition for having a highly protected mathematical algorithm against any opponent or cryptanalysis
