论文摘要
芯片上芯片（SOC）的启用信任区的安全性在数年中一直在越来越多的关注。主要是因为这种类型的SOC可以在服务器或云中越来越多的应用中找到。内部通信层是异质SOC的主要要素之一。实际上，所有数据都通过了。监视和控制内部通信的通信使系统损坏之前可以抵御攻击。在本文中，我们研究了在受信任的执行环境（TEE）中执行的安全软件与异质SOC的安全逻辑部分之间加密数据交换的可行性。实验是使用Xilinx Zynq-7010 SOC和两个轻巧的流密码进行的。我们表明，使用轻质流密码是一个有效的解决方案，没有过多的开销。
Security in TrustZone-enabled heterogeneous system-on-chip (SoC) is gaining increasing attention for several years. Mainly because this type of SoC can be found in more and more applications in servers or in the cloud. The inside-SoC communication layer is one of the main element of heterogeneous SoC; indeed all the data goes through it. Monitoring and controlling inside-SoC communications enables to fend off attacks before system corruption. In this article, we study the feasibility of encrypted data exchange between the secure software executed in a trusted execution environment (TEE) and the secure logic part of an heterogeneous SoC. Experiment are done with a Xilinx Zynq-7010 SoC and two lightweight stream ciphers. We show that using lightweight stream ciphers is an efficient solution without excessive overheads.
