Abstract

Abstract: Assuring functional safety and IT security is rapidly becoming an essential key challenge to the design of any connected smart product and industrial manufacturing system. This paper proposes an architectural approach to the integrated consideration of functional safety and IT security requirements in the design process of smart products and the (Industrial) Internet of Things (IIoT). Based on axiomatic design and signal flow analysis, it shows that such requirements have related impacts on system architectural design choices rendering integrated design necessary to meet the desired risk reduction levels effectively and efficiently. A case study in the automotive domain is presented in order to illustrate and validate the proposed approach.
