A Security Aware Design Space Exploration Framework

Abstract:
System designers are often faced with a huge variety of alternative hardware platforms and architectures, when designing new products. Especially the various options for allocating a set of tasks to processing units greatly influences the overall system performance and power consumption. As the possible design space is too complex for manual evaluation, automatic Design Space Exploration (DSE) tools are used for selecting first system designs. These tools assess the various mappings between tasks and processing units. They target the best allocation, optimizing the system’s performance and power consumption, while considering other predefined design constraints. Traditionally, security requirements do not belong to the set of design constraints these tools deal with. Thus, security requirements must be introduced manually, which might induce additional costs to the overall project. To enable security-by-design using DSE, the Security Aware Design Space Exploration (SADSE) Framework was developed. This framework allows the integration of attack scenarios and security requirements, as well as platform security features into the DSE, at a level of detail not yet considered by other tools. SADSE allows an optimal allocation of tasks onto hardware platforms, while satisfying predefined security constraints. This paper shows how security requirements and attack vectors are modeled in SADSE, followed by the evaluation of a keyless entry system use case, where the tool finds a secure mapping of tasks to processing units.
