Contemporary integrated circuits are designed and manufactured in a globalized environment leading to concerns of piracy, overproduction and counterfeiting. One class of techniques to combat these threats is logic encryption. Logic encryption modifies an IC design such that it operates correctly only when a set of newly introduced inputs, called key inputs, are set to the correct values. In this paper, we use algorithms based on satisfiability checking (SAT) to investigate the security of logic encryption. We present a SAT-based algorithm which allows an attacker to "decrypt" an encrypted netlist using a small number of carefully-selected input patterns and their corresponding output observations. We also present a "partial-break" algorithm that can reveal some of the key inputs even when the attack is not fully successful. We conduct a thorough evaluation of our attack by examining six proposals for logic encryption from the literature. We find that all of these are vulnerable to our attack. Among the 441 encrypted circuits we examined, we were able to decrypt 418 (95%). We discuss the strengths and limitations of our attack and suggest directions that may lead to improved logic encryption algorithms.

With the development of the Internet of Things, the Wireless Senor Network has been paid increasing attention. It can not only perceive the physical world, collect and transmit information, but also brings new problems in the security of information. As the nodes of Wireless Sensor Network are limited by hardware resources and energy, how to select fast and energy-saving encryption algorithms in terms of Wireless Sensor Network is very important. This paper constructs a test framework for comparing the energy consumption, time efficiency, and space efficiency and then tests parameters of multiple algorithms in the same application environment. The results provide a basis for choosing suitable algorithms for the Wireless Sensor Network.

The microgrid (MG) provides a viable pathway for integrating distributed energy resources (DERs). With the development of the electricity market, the current challenge lies in guiding DERs to enter the market correctly and establishing a fair and equitable market order. In this paper, a virtual power plant (VPP) model is established by aggregating multi-microgrids (MMGs) with an architecture that combines centralized management of the VPP and blockchain-based decentralized transactions between MGs. Market transactions increase the complexity of energy interactions between MGs in the VPP and generate a significant amount of associated data, thereby imposing higher demands on the fairness of transactions and data privacy. In this regard, a blockchain-based optimization method for the operation and trading among MMGs is developed. We design a priority-based bilateral auction model and introduce a malicious bid penalty mechanism to ensure the orderliness of energy interactions between different MGs. To ensure the privacy of transaction prices, a cryptographic algorithm based on Pedersen commitment is proposed, allowing the upper VPP to supervise the legality of electricity settlements under private prices. In the case study, the proposed model is solved by the Equilibrium Optimizer and CPLEX solver. The results show that the proposed method performs well in reducing costs, restraining malicious bids, and protecting price privacy, which is conducive to the healthy development of the electricity market.

Several security mechanisms have been introduced to address the need for reliable and efficient security schemes in resource limited Wireless Sensor Networks (WSNs). Limitations in processing speed, battery power, bandwidth and memory constrain the applicability of existing cryptographic algorithms in WSNs. Accordingly, it is necessary to assess the performance tradeoffs of the cryptographic algorithms to provide a better understanding of the security cost. In this paper, we have studied three block cipher algorithms: Advanced encryption Standard (AES), RC5, and RC6. We have measured and compared their memory and energy consumption in the Mica2 sensor motes. Experimentation results show that AES has higher memory and energy requirements than RC5 and RC6. RC6 has higher operation time and power consumption while RC5 is the most time-and energy-efficient block cipher and thus the best cipher solution for devices with limited resources.

A cyberattack is a serious crime that could affect medical organizations. These attacks could affect medical organization sensitive data disclosure, loss of organization data, or the business's continuity. The Man-in-The-Middle (MITM) attack is one of the threats that could impact medical organizations. It happens when unapproved outsiders break into the traffic between two parties that think they are conversing directly. At the same time, the adversary can access, read, and change secret information. Because of that, medical organizations lose confidentiality, integrity, and availability. Data encryption is a solution that changes vital information to unreadable by unauthorized and unintended parties. It could involve protecting data with cryptography, usually by leveraging a scrambled code. Only the individuals with the decoding key can read the information. There is no full protection due to the variety of MITM attacks. Each encryption algorithm has its advantages and disadvantages, like the speed of encryption and decryption, strength of the algorithm, and the cipher type. This research investigates the MITM attacks and comprehensively compares the Rivest Shamir Adleman algorithm and the Elliptic Curve Cryptography algorithm.

The rise of low-power, cost-efficient internet-connected devices has led to a need for lightweight cryptography. The lightweight block cipher PRIDE, designed by Martin R. Albrecht, is one of the most efficient ciphers designed for IoT-constrained environments. It is useful for connected devices, requires fewer resources to implement, and has high performance. PRIDE is a software-oriented lightweight cipher optimized for microcontrollers. This paper focuses on the FPGA implementation of the PRIDE cipher by keeping throughput, energy, and power consumption metrics focused. The paper also presents a novel and simpler diagrammatical view of a Matrix Layer implementation of the PRIDE cipher. We also implemented the PRESENT cipher using the same metrics. We analyzed different design metrics on Field Programmable Gate Arrays (FPGAs) and compared the metrics of the PRIDE implementation with the well-known cipher PRESENT. This gives us an insight into the efficiency and reliability of PRIDE in IoT-constrained environments. We also proposed different architectures of the PRIDE cipher for 16-bit and 32-bit datapaths. © 2024

In this paper, an improved multi-dimensional hyperchaotic system derived from the logistic map and the ICMIC based on closed-loop coupling (LICC hyperchaotic system) is proposed and it is used in the design of selective image encryption. The performance analysis shows that the LICC hyperchaotic system with a strong coupling degree has parameters whose value can be set more flexibly and can generate a wider and more uniform distribution of chaotic sequences. Then selective image encryption is proposed. Firstly, an adaptive pseudo-random sequence generator based on hash function is designed to ensure the difference of sequences used in different encryption steps. Second, a novel bit-level scrambling is designed to increase the encryption speed. Finally, an efficient rule to select image blocks with weak security is proposed and the second step of the encryption is performed at the selected blocks of the image to ensure security. The encryption performance and security analysis show that the proposed encryption algorithm based on an improved hyperchaotic system is secure enough to resist several types of attacks.

Advanced encryption standard based on key dependent S-Box cube

引用

IET INFORMATION SECURITY 2019年第6期13卷 552-558页

The advanced encryption standard (AES) is the most encryption algorithm used around the world. This fact made it coveted by several cryptanalysis attacks. Some of them succeed to reveal certain weakness, due to its static parameters known by the public mass. The substitution box (S-Box) is among the most sensitive parameters of this standard, which plays a crucial role in the protection against these attacks. In this study, a new version of AES is introduced, which uses a set of AES-like S-Boxes instead of the original one. These S-Boxes, generated from different irreducible polynomials, are dynamically chosen, depending on the encryption key. This introduction is conducted by the design and the implementation of a new block cipher version of AES, based on a key dependent S-Box cube. Where a cube of six interchangeable S-Boxes key-dependently generated is constructed. This cube determines the active S-Box for a given round, through its random rotations guided by the round key. Furthermore, the improvement of the cryptographic robustness, provided by this method is demonstrated. This is accomplished through a comparison with the original AES, in terms of statistical and cryptographic randomness properties.
