Distortion-Based Lightweight Security for Cyber-Physical Systems

Security in Cyber-Physical Systems

Information Security is a domain of IT that has a well developed body of knowledge, and a cadre of practitioners with significant experience in securing IT systems. Cyber Physical Systems (CPS) also has a well developed body of knowledge and a well trained cadre of professionals that have been successfully running systems for years. These are two separate groups that would benefit from working ...

Cyber-Physical Systems Security for Smart Grid

Designed-in Security for Cyber-Physical Systems

T here are at least two types of security vulnerabilities: flawed or insufficient software behavior specifications that allow compromise—for example, authentication that is lacking or that can be spoofed—and incorrect implementation of specifications— buffer overflows being a classic example and Heartbleed being a notable recent one. The sad truth is that the state of the art in specification d...

Challenges in Security for Cyber-Physical Systems

The design of security for cyber-physical systems must take into account several characteristics common to such systems. Among these are feedback between the cyber and physical environment, distributed management and control, uncertainty, real-time requirements, and geographic distribution. This paper discusses these characteristics and suggests a design approach that better integrates security...

Enhancing Security in Cloud-based Cyber-physical Systems

Cyber-physical systems combine traditional data-processing systems with physical actuation capabilities. The physical aspect introduces new physical risks beyond the typical cyber risks related to information security. Cyber physical systems have an additional physical interface that must be protected from attacks. Furthermore, the physical actuation capabilities increase the potential amount o...
