A Secure Messaging for Internet of Things Protocol based RSA and DNA Computing for Video Surveillance System

Video surveillance is one of the most secure and protected applications in modern cities and facilities. Local video processing and decision making will reduce the time and cost of such systems. For distributed camera monitoring system over a wide area, data transfer over the internet become essential, and hence the system would be an internet of things application since these nodes need to communicate with each other. In this work, an encryption-decryption algorithm based on RSA and DNA computing is used for messages transfer over MQTT protocol between the distributed nodes of camera system which is equipped with an intelligent processing unit. The system has been implemented using open source python language with the Linux operating system.
