"The SESAMO project addresses the root causes of problems arising with convergence of safety and security in embedded systems at architectural level, where subtle and poorly understood interactions between functional safety and security mechanisms impede system definition, development, certification, and accreditation procedures and standards. Intense market innovation is being held back by this root cause: the absence of a rigorous theoretical and practical understanding of safety and security feature interaction.The proposed solution is to develop a component-oriented design methodology based upon model-driven technology, jointly addressing safety and security aspects and their interrelation for networked embedded systems in multiple domains (e.g., avionics, transportation, industry control).Key elements of the SESAMO approach are:• a methodology to reduce interdependencies between safety and security mechanisms and to jointly ensure their properties• constructive elements for the implementation of safe and secure systems• procedures for integrated analysis of safety and security• an overall design methodology and tool-chain utilizing the constructive elements and integrated analysis procedures to ensure that safety and security are intrinsic characteristics of the system.The relevance of the SESAMO results is guaranteed by the involvement of large partners with significant economic interests in safety and security critical systems in the use case domains: automotive, aerospace, energy, mobile medical, and metropolitan rail transport; a sound group of technology providers (including SMEs); and prestigious research entities (academia and institutes) with deep and complementary multi-domain expertise.SESAMO will enable cost-efficient and systematic design, analysis, development, and assessment of distributed safety and security critical embedded systems. The results will have broad, cross-domain applicability in numerous strategic sectors of European industry.Approved by ARTEMIS-JU on 22/02/2012, Amendment 1 approved by ARTEMIS-JU on 27/02/2014, Amendment 2 approved by ECSEL-JU on 18/02/2015."
