“…Son et al [41] and Völp et al [70] examined the exploitation of timing channels in real-time scheduling. Bao et al [71] introduce a scheduling algorithm for soft real-time systems (where some tasks can miss deadlines) and provide a trade-off between thermal side-channel information leakage and the number of deadline misses. Their exists other work [56] that studies the robustness of AES secret keys against differential power analysis (DPA) [72] attacks.…”

Modern embedded and cyber-physical systems are ubiquitous. Many critical cyber-physical systems have real-time requirements (e.g., avionics, automobiles, power grids, manufacturing systems, industrial control systems, etc.). Recent developments and new functionality require real-time embedded devices to be connected to the Internet. This gives rise to the real-time Internet-of-things (RT-IoT) that promises a better user experience through stronger connectivity and efficient use of next-generation embedded devices. However, RT-IoT are also increasingly becoming targets for cyber-attacks, which is exacerbated by this increased connectivity. This paper gives an introduction to RT-IoT systems, an outlook of current approaches and possible research challenges towards secure RT-IoT frameworks.

“…Therefore, it is imperative for RTESs to protect critical information and against the potential attacks. At present, most researchers focus on designing the security-aware techniques for handling attacks such as SCAs, [1][2][3][4][5] LMFAs, 6 SLCAs and CIAs, 7,8 which are brie°y introduced in Table 2. The details of these attacks and their corresponding solutions are given in the following sections.…”

“…Considerable research e®orts have been devoted to the designing of a secure RTES, which can be divided into three categories. The¯rst category to realize a secure system is studying and simulating the common security attacks such as sidechannel attack (SCA), [1][2][3][4][5] level-based multi-fault attacks (LMFAs), 6 system-level cyber attacks (SLCAs), code injection attacks (CIAs), 7,8 etc. The second category to realize a secure system is providing security-guaranteed services such as securityaware model and framework, [9][10][11][12][13] security-driven hardware design, 14,15 encryption algorithm.…”

With the rapid development of embedded systems, users and services have been greatly facilitated while also experiencing security threats as a result of cyber-attacks and system vulnerabilities. Currently, the real-time embedded system (RTES) focus is to deal with these security issues. In this paper, we introduce a short review of security-aware techniques for RTES. We mainly discuss two common approaches to improve the security of RTESs. The first approach is achieved by exploring specific attacks. The second approach is realized by deploying security-guaranteed services. However, improving the security of embedded systems may cause excessive energy consumption at the same time. Therefore, we investigate the secure and energy-aware RTESs on a wide range of research. In addition, we study a number of common applications used in secure RETSs. This paper stands for providing awareness and better understanding of the current RTES research status as well as technical theory behind it. Hence, the RTES security issues are resolved.

Side channels remain a challenge to information flow control and security in modern computing platforms. Resource partitioning techniques that minimise the number of shared resources among processes are often used to address this challenge. In this work, we focus on multicore platforms and we demonstrate that even seemingly strong isolation techniques based on dedicated cores and memory can be circumvented through the use of thermal side channels. Specifically, we show that the processor core temperature can be used both as a side channel as well as a covert communication channel even when the system implements strong spatial and temporal partitioning. Our experiments on an x86-based platform demonstrate covert thermal channels that achieve up to 12.5 bps and a weak side channel that can detect processes executed on neighbouring cores. This work therefore shows a limitation in the isolation that can be achieved on existing multi-core systems.
