A Flexible Ultralight Hardware Security Module for EPC RFID Tags

Due to the rapid growth of using Internet of Things (IoT) devices in daily life, the need to achieve an acceptable level of security and privacy for these devices is rising. Security risks may include privacy threats like gaining sensitive information from a device, and authentication problems from counterfeit or cloned devices. It is more challenging to add security features to extremely constrained devices, such as passive Electronic Product Code (EPC) Radio Frequency Identification (RFID) tags, compared to devices that have more computational and storage capabilities. EPC RFID tags are simple and low-cost electronic circuits that are commonly used in supply chains, retail stores, and other applications to identify physical objects. Most tags today are simple "license plates" that just identify the object they are attached to and have minimal security. Due to the security risks of new applications, there is an important need to implement secure RFID tags. Examples of the security risks for these applications include unauthorized physical tracking and inventorying of tags. The current commercial RFID tag designs use specialised hardware circuits approach. This approach can achieve the lowest area and power consumption; however, it lacks flexibility. This thesis presents an optimized application-specific instruction set architecture (ISA) for an ultralight Hardware Security Module (HSM). HSMs are computing devices that protect cryptographic keys and operations for a device. The HSM combines all security-related functions for passive RFID tag. The goal of this research is to demonstrate that using an application-specific instruction set processor (ASIP) architecture for ultralight HSMs provides benefits in terms of trade-offs between flexibility, extensibility, and efficiency. Our novel application specific instruction-set architecture allows flexibility on many design levels and achieves acceptable security level for passive EPC RFID tag. Our solution moves a major design effort from hardware to software, which largely reduces the final unit cost. Our ASIP processor can be implemented with 4,662 gate equivalent units (GEs) for 65 nm CMOS technology excluding cryptographic units and memories. We integrated and analysed four cryptographic modules: AES and Simeck block ciphers, WG-5 stream cipher, and ACE authenticated encryption module. Our HSM achieves very good efficiencies for both block and stream ciphers. Specifically for the AES cipher, we improve over a previous programmable AES implementation result by 32x. We increase performance dramatically and increase/decrease area by 17.97/17.14% respectively. These results fulfill the requirements of extremely constrained devices and allow the inclusion of cryptographic units into the datapath of our ASIP processor

A Survey of ARX-based Symmetric-key Primitives

Addition Rotation XOR is suitable for fast implementation symmetric –key primitives, such as stream and block ciphers. This paper presents a review of several block and stream ciphers based on ARX construction followed by the discussion on the security analysis of symmetric key primitives where the best attack for every cipher was carried out. We benchmark the implementation on software and hardware according to the evaluation metrics. Therefore, this paper aims at providing a reference for a better selection of ARX design strategy

Intelligent Sensor Networks

In the last decade, wireless or wired sensor networks have attracted much attention. However, most designs target general sensor network issues including protocol stack (routing, MAC, etc.) and security issues. This book focuses on the close integration of sensing, networking, and smart signal processing via machine learning. Based on their world-class research, the authors present the fundamentals of intelligent sensor networks. They cover sensing and sampling, distributed signal processing, and intelligent signal learning. In addition, they present cutting-edge research results from leading experts

Proceedings of the 5th International Workshop on Reconfigurable Communication-centric Systems on Chip 2010 - ReCoSoC\u2710 - May 17-19, 2010 Karlsruhe, Germany. (KIT Scientific Reports ; 7551)

ReCoSoC is intended to be a periodic annual meeting to expose and discuss gathered expertise as well as state of the art research around SoC related topics through plenary invited papers and posters. The workshop aims to provide a prospective view of tomorrow\u27s challenges in the multibillion transistor era, taking into account the emerging techniques and architectures exploring the synergy between flexible on-chip communication and system reconfigurability

Embedded System Design

A unique feature of this open access textbook is to provide a comprehensive introduction to the fundamental knowledge in embedded systems, with applications in cyber-physical systems and the Internet of things. It starts with an introduction to the field and a survey of specification models and languages for embedded and cyber-physical systems. It provides a brief overview of hardware devices used for such systems and presents the essentials of system software for embedded systems, including real-time operating systems. The author also discusses evaluation and validation techniques for embedded systems and provides an overview of techniques for mapping applications to execution platforms, including multi-core platforms. Embedded systems have to operate under tight constraints and, hence, the book also contains a selected set of optimization techniques, including software optimization techniques. The book closes with a brief survey on testing. This fourth edition has been updated and revised to reflect new trends and technologies, such as the importance of cyber-physical systems (CPS) and the Internet of things (IoT), the evolution of single-core processors to multi-core processors, and the increased importance of energy efficiency and thermal issues
