Design and Develop a Secure CPS Flexible Framework to Improve the Cyber Security using a New Security Algorithm

CPS is an active system that transforms a physical system into a computerized system through the use of technology and a set of instructions that govern how the system operates. Because of CPS, even the most basic of equipment can function as a smart device. For the most part, these devices have limited processing capabilities, operate at low power, and have a small amount of storage space. The Internet of Things integrates everyday “things” with the internet. Computer Engineers have been adding sensors and processors to everyday objects since the 90s. However, progress was initially slow because the chips were big and bulky. Low power computer chips called RFID tags were first used to track expensive equipment. As computing devices shrank in size, these chips also became smaller, faster, and smarter over time. Existing security mechanisms works efficiently on high end CPS devices. The performance analysis also shows these algorithms perform well against different attacks. But when constraint-based applications come into the picture it was found that existing mechanism identifies many installation and configuration problems. Even these algorithms if installed in constraint-based application overall performance of the system degrade. To overcome these problems, we proposed a secure CPS flexible framework to improve the cyber security using a new session key security algorithm. So proposed algorithm must focus on constraint-based applications. It must support all the parameters of constraint-based devices. Key generated through algorithm must follows the key management design principles which includes scalability, freshness and accountability.
