Abstract

There are numerous techniques, methods and tools to promote the security of a digital system, however, each day the mechanisms of attack evolve and are integrated, creating separate spheres of combined attacks. In this context, this paper presents an embedded security system (into a SoC system) that has as main goal an integration of the security services. It reaches an improved performance and prevents malicious attacks on systems and networks. The SoC prioritizes the implementation of dedicated functions in hardware as cryptographic algorithms, communication interfaces, among others. In our prototype, initially, the flow control functions and settings are running in software. This article shows the architecture, functionality and performance of the system developed, and we discuss a real implementation in FPGA.
