DNA cryptography is one of the promising fields in cryptographic research which emerged with the evolution of DNA computing. In this era, end to end transmission of secure data by ensuring confidentiality and authenticity over the networks is a real challenge. Even though various DNA based cryptographic algorithms exists, they are not secure enough to provide better security as required with today's security requirements. Hence we propose a cryptographic model which will enhance the message security. A new method of round key selection is used, which provides better and enhanced security against intruder's attack. The crucial attraction of this proposed model is providing multi level security of 3 levels with round key selection and message encryption in level 1, 16x16 matrix manipulation using asymmetric key encryption in level 2 and shift operations in level 3. Thus we design a system with multi level encryption without compromising complexity and size of the cipher text.
