Towards cognitive security systems

Abstract

This talk addresses the changing world of security systems, and a possible approach to their improvement. Since the scientific, technical, industrial, business, and social worlds have changed from physically isolated systems to electronically interconnected system-of-systems (SoS), the functioning of such a SoS depends critically on its operational robustness and security. In the previous physically-isolated world, robust static security for selected matched problems was often sufficient. Today, we need a new approach to providing security, because even adaptive security is insufficient. This new approach is termed here a cognitive security system. The talk will cover three major issues. First, the talk starts from a review of the existing security systems, with their problems and required solutions, as well as their vulnerabilities, attacks, and defences. Second, it provides a review of decision-making systems, including dynamic and dynamical systems, complex systems, adaptive systems, autonomic systems and their attributes, symbiotic systems, and finally special attention is given to cognitive dynamic systems as defined by Wang's cognitive informatics [1-4], Kinsner cognitive machines, [5], Haikonen conscious machines [6], and Haykin cognitive dynamic systems [7]. This review ends with a model of cognitive security system. This model has a feature based on polyscale analysis and synthesis never reported before. Finally, examples of security-related cognitive static and dynamic systems developed in our research group are presented, including wavelet-packet fingerprint compression for data mining, watermarking and steganography, a new chaotic cryptography system, and new polyscale analysis for SmartGrid2.
