Information and communication technologies (IT) and IT-based instrumentation and control (I&C) systems, hardware and software components are analyzed in context of “green” paradigm. Green IT paradigm is formulated as a Cartesian product of a pair “external (E) and internal (I) aspects of IT and computer-based I&Csystems” and a pair “power (recourse) consumption minimization (Rmin) and safety maximization (Smax)”. In the paper we discuss main research challenges and development solutions, education and training activities in the domain of green and safe computing and communication. Finally, we report results of EU-TEMPUS projects in the area of safe and green ITs and define models of academia and industry cooperation for excellence, innovations and knowledge exchange.

The application of complex electronic components such as systems-on-chips (including systems-on-programmable-chips using field programmable gate arrays (FPGAs)) in industrial instrumentation and control systems (I&Cs) causes risks for ensuring of safety. Nuclear power plant (NPP) I&C projects on FPGA are complex solutions which include both software and hardware components. Information security (system’s ability to protect the information and data from unauthorized access and modification) is a subordinate property with respect to safety of many I&Cs, primarily to the NPP reactor trip systems. Such hierarchy may be taken into account by implementation of security informed safety (SIS) approach. Recent events like Stuxnet or Duqu showed vulnerabilities in industrial embedded IT-Systems. In order to remove or reduce security risks, which could increase overall safety risk, the holistic analytical technique are necessary. The goal of the paper is to present the technique for of SIS-based assessment of the NPP I&C systems. The proposed SIS-oriented method of NPP I&C systems assessment includes the models and techniques. To decrease the risk of manual errors, the tool for the SIS-oriented assessment automation is described. The tool is based on joint use of abovementioned models and techniques, is proposed. The tool allows conducting the joint use of the following analysis techniques: GAP and IMECA.

The paper discusses importance of assessment of interference degree for various attributes of safety-critical systems, including safety and security, proposes applicable metrics, as well as represents an approach to assessment of safety-critical systems. Such approach relies on performance of gap analysis and consideration of influence of human, technique and tool. The approach is applicable to various safety-critical systems, including FPGA-based instrumentation and control (I&C) systems. Requirements of US Nuclear Regulatory Commission to security assessment and assurance for safety critical NNP I&C systems are analyzed. Profiling of the requirements considering features of FPGA-based I&Cs is described. As a case-study some results of security assessing for FPGA platform using Intrusion Modes and Effect Criticality Analysis (IMECA) are illustrated.
