Abstract

Many of the current electronic systems embedded in a SoC (System-on- Chip) are used to capture, store, manipulate and access critical data, as well as to perform other key functions. In such a scenario, security is considered as an important issue. The Network-on-chip (NoC), as the foreseen communication structure of next-generation SoC devices, can be used to efficiently incorporate security. Our work proposes the implementation of QoSS (Quality of Security Service) to overcome present SoC vulnerabilities. QoSS is a novel concept for data protection that introduces security as a dimension of QoS. In this paper, we present the implementation of two security services (access control and authentication), that may be configured to assume one from several possible levels, the implementation of a technique to avoid denial-of-service (DoS) attacks, evaluate their effectiveness and estimate their impact on NoC performance.
