Special Issue Information

Dear Colleagues,

Today’s embedded systems are, to an increasing degree, being deployed in contexts where the safety and security of a system are paramount. The systems need to be demonstrably safe, meaning that they should not instigate an unacceptable risk to humans, environment, or equipment. Often, an independent certification agency must assess safety. At the same time, systems must be secure, meaning that they should be resilient to tampering and malicious attempts to access or control the system. In the connected world, security measures to prevent attacks of the Internet are necessary. Thread and hazard analysis of embedded systems usually depend on the recognition of vulnerable software and hardware components, where the failure of these can cause accidents or successful attacks. While both safety and security are difficult and expensive to achieve in their own rights, their combination in provable safe and secure embedded systems remains largely unsolved. Hence, this Special Issue solicits novel research in topics that include, but are not limited to:

  • modeling of safety and security concerns in embedded systems
  • interdependencies between safety and security in embedded systems
  • integrated approaches safety and security
  • security in safety-critical systems
  • run-time mechanisms in hardware and software to support safety and security
  • safety and security in parallel and/or heterogeneous computing platforms
  • methods, tools, and techniques for modeling, design, and verification of safe and secure embedded systems
  • implications of regulation and certification on safety and security in embedded systems
  • thread and hazard analysis of hardware and software components
  • fault tolerant designs for safe and secure embedded systems
  • hardware and software co-design and specialization for safe and secure embedded systems

Soft error is a key challenge in computer systems. Without soft error mitigation, control flow error (CFE) can lead to system crash. Signature-based CFE monitoring scheme is a representative technique for detecting CFEs during runtime. However, most of the signature-based CFE monitoring schemes proposed thus far are based on a single thread. Currently, the widely used multi-threaded and multi-core environments have greatly improved the performance of the computing system, but, if the these schemes are applied in these environments, performance improvement is difficult to achieve, or rather performance degradation may occur. In this paper, we propose a separate signature-based CFE monitoring (SSCFM) scheme that separates the signature update and the signature verification on the thread level. The signature update is combined with application thread and signature verification and executed on separate monitor threads, so that we can expect performance improvements in multi-threaded or multi-core environments. Furthermore, the SSCFM scheme can fully cover inter-procedural CFE not covered by many signature-based CFE monitoring schemes by using inter-procedural control flow analysis. With the proposed SSCFM scheme, the execution time overhead is reduced by approximately 26.67% on average from the SEDSR scheme, and the average CFE detection rate with SSCFM is approximately 93.69%. In addition, this paper also introduces the LLVM compiler-based SSCFM generator that makes it easy to apply the SSCFM scheme to software applications. Full article

At present, the embedded systems are facing various kinds of attacks, especially for the data stored in the external memories. This paper presents a hardware-enhanced protection method to protect the data integrity and confidentiality at runtime, preventing the data from spoofing attack, splicing attack, replay attack, and some malicious analysis. For the integrity protection, the signature is calculated by the hardware implemented Lhash engine before the data sending off the chip, and the signature of the data block is recalculated and compared with the decrypted one at the load time. For the confidentiality protection, an AES encryption engine is used to generate the key stream, the plain data and the cipher data can translate through a simple XOR operation. The hardware cryptographic engines are optimized to work simultaneously with the memory access operation, which reduces the hardware overhead and the performance overhead. We implement the proposed architecture within OR1200 processor on Xilinx Virtex 5 FPGA platform. The experiment results show that the proposed hardware-enhanced protection method can preserve the integrity and confidentiality of the runtime data in the embedded systems with low power consumption and a marginal area footprint. The performance overhead is less than 2.27% according to the selected benchmarks. Full article

Nowadays, three-dimensional (3D) printing technology is applied to many areas of life and changes the world based on the creation of complex structures and shapes that were not feasible in the past. But, the data of 3D printing is often attacked in the storage and transmission processes. Therefore, 3D printing must be ensured security in the manufacturing process, especially the data of 3D printing to prevent attacks from hackers. This paper presents a security solution for 3D printing based on two-dimensional (2D) slices encryption. The 2D slices of 3D printing data is encrypted in the frequency domain or in the spatial domain by the secret key to generate the encrypted data of 3D printing. We implemented the proposed solution in both the frequency domain based on the Discrete Cosine Transform and the spatial domain based on geometric transform. The entire 2D slices of 3D printing data is altered and secured after the encryption process. The proposed solution is responsive to the security requirements for the secured storage and transmission. Experimental results also verified that the proposed solution is effective to 3D printing data and is independent on the format of 3D printing models. When compared to the conventional works, the security and performance of the proposed solution is also better. Full article

Improving network security is a difficult problem that requires balancing several goals, such as defense cost and need for network efficiency, to achieve proper results. Modeling the network as a game and using optimization problems to select the best move in such a game can assist network administrators in determining an ideal defense strategy. However, most approaches for determining optimal game solutions tend to focus on either single objective games or merely scalarize the multiple objectives to a single of objective. In this paper, we devise a method for modeling network attacks in a zero-sum multi-objective game without scalarizing the objectives. We use Pareto Fronts to determine the most harmful attacks and Pareto Optimization to find the best defense against those attacks. By determining the optimal solutions through those means, we allow network administrators to make the final defense decision from a much smaller set of defense options. The included experiment uses minimum distance as selection method and compares the results with a minimax algorithm for the determination of the Nash Equilibrium. The proposed algorithm should help network administrators in search of a hands-on method of improving network security. Full article
