The integration of multicore processors and peripherals from multiple intellectual property core providers as hardware components of IoT multiprocessor systems-on-chip (SoC) represents a source of security vulnerabilities for the in-chip communication. This paper describes the concept and the practical results of a SoC security implementation that is illustrative for IoT applications. The mechanism employed in this approach uses physically unclonable functions (PUF) and symmetric cryptography in order to encrypt the transferred messages within the SoC between the microprocessor and its peripherals. The mechanism is experimentally validated at FPGA level, the paper describing also an implementation scenario for an IoT ARM based device.

来自多个知识产权核心提供商的多核处理器和外围设备的集成作为物联网多处理器片上系统（SoC）的硬件组件，代表了片内通信安全漏洞的来源。本文介绍了SoC安全实现的概念和实际结果，可为IoT应用提供说明。此方法中使用的机制使用物理上不可克隆的功能（PUF）和对称加密，以便对SoC及其在微处理器及其外围设备之间的消息进行加密。该机制已在FPGA级别进行了实验验证，该论文还描述了基于IoT ARM的设备的实现方案。
