Cataloged from PDF version of thesis. Includes bibliographical references (pages 45-46). Cryptography allows our data to be transmitted without giving sensitive information away. This is the art of hiding the information from the malicious third party and make the data accessible to only the sender and the receiver. Building a complex cryptosystem has always been a challenge which can provide relentless security and is infeasible to break. This paper discusses about a hybrid cryptosystem which is inspired from the concepts of DNA cryptography and it is further strengthened using multiple components. A random key is used which is generated using run test of randomness, different DNA encoding combinations and a state changing random state mealy machine is used for further strengthening the security. This paper provides a detailed discussion regarding every components the authors used to build the system and also discusses about the combined system that has been built. This paper also discusses about the effectiveness and the performance of the proposed system to give an overview of its security measures and also provides some comparative analysis with existing works to back the claim on improved security features.
