In computer security, cryptographic algorithms and protocols are required to ensure security of data and applications. This research investigates techniques to reduce the energy consumed by cryptographic hash functions. The specific hash functions considered are Message Digest-2 (MD2), Message Digest-5 (MD5), Secure Hash Algorithm-1 (SHA-1) and Secure Hash Algorithm-2 (SHA-2). The discussion around energy conservation in handheld devices like laptops and mobile devices is gaining momentum. Research has been done at the hardware and operating system levels to reduce the energy consumed by these devices. However, research on conserving energy at the application level is a new approach. This research is motivated by the energy consumed by anti-virus applications which use computationally intensive hash functions to ensure security. To reduce energy consumption by existing hash algorithms, the generic energy complexity model, designed by Roy et al. [Roy13], has been applied and tested. This model works by logically mapping the input across the eight available memory banks in the DDR3 architecture and accessing the data in parallel. In order to reduce the energy consumed, the data access pattern of the hash functions has been studied and the energy complexity model has been applied to hash functions to redesign the existing algorithms. These experiments have shown a reduction in the total energy consumed by hash functions with different degrees of parallelism of the input message, as the energy model predicted, thereby supporting the applicability of the energy model on the different hash functions chosen for the study. The study also compared the energy consumption by the hash functions to identify the hash function suitable for use based on required security level. Finally, statistical analysis was performed to verify the difference in energy consumption between MD5 and SHA2.

This work presents recent developments in hashing algorithm design. Hashing is the process of creating a short digest (i.e., 64 bits) for a message of arbitrary length, for exam- ple 20 Mbytes. Hashing algorithms were first used for sear- ching records in databases; they are central for digital si- gnature applications and are used for authentication without secrecy. Covering all practical and theoretical issues related to the design of secure hashing algorithms the book is self contained; it includes an extensive bibliography on the topic.

Energy consumption by various modern symmetric key encryption protocols (DES, 3-DES, AES and, Blowfish) is studied from an algorithmic perspective. The work is directed towards redesigning or modifying the underlying algorithms for these protocols to make them consume less energy than they currently do. This research takes the approach of reducing energy consumption by parallelizing the consecutive memory accesses of symmetric key encryption algorithms. To achieve parallelization, an existing energy complexity model is applied to symmetric key encryption algorithms. Inspired by the popular DDR3 architecture, the model assumes that main memory is divided into multiple banks, each of which can store multiple blocks. Each block in a bank can only be accessed from a cache of its own, that can hold exactly one block. However all the caches from different banks can be accessed simultaneously. In this research, experiments are conducted to measure the difference in energy consumption by varying the level of parallelization, i.e. variations of, number of banks that can be accessed in parallel. The experimental results show that the higher the level of parallelism, smaller is the energy consumption.

After a brief introduction to low-power VLSI design, the design space of ASIP instruction set architectures (ISAs) is introduced with a special focus on important features for digital signal processing. Based on the degrees of freedom offered by this design space, a consistent ASIP design flow is proposed: this design flow starts with a given application and uses incremental optimization of the ASIP hardware, of ASIP coprocessors and of the ASIP software by using a top-down approach and by applying application-specific modifications on all levels of design hierarchy. A broad range of real-world signal processing applications serves as vehicle to illustrate each design decision and provides a hands-on approach to ASIP design. Finally, two complete case studies demonstrate the feasibility and the efficiency of the proposed methodology and quantitatively evaluate the benefits of ASIPs in an industrial context.

The Internet of Things (IoT) has introduced a vision of an Internet where computing and sensing devices are interconnected. Digitally connected devices are encroaching on every aspect of our lives, including our homes, cars, offices, and even our bodies. Researchers estimate that there will be over 50 billion wireless connected devices by 2020 [1]. On one hand, the IoT enables fundamentally new applications, but on the other, these devices are attractive targets for cyber attackers, thus making IoT security a major concern. Datagram Transport Layer Security (DTLS) is considered to be one of the most suited protocols for securing the IoT. However, computation and communication overheads make it very expensive to implement DTLS on resource-constrained IoT sensor nodes. In this work, we profile the energy costs of DTLS version 1.3, using experimental models for cryptographic computations and radio-frequency (RF) communications. Based on this analysis, we propose protocol optimizations that can reduce the overall energy consumption of DTLS up to 45%, while still maintaining the same security strength of the standard DTLS. We discuss energy-efficient architectures for implementing the standard cryptographic primitives AES (Advanced Encryption Standard), SHA (Secure Hash Algorithm) and ECC (Elliptic Curve Cryptography) in hardware. Our hardware can provide more than 2,500 times reduction in energy consumption compared to traditional software implementations. These hardware primitives are integrated with dedicated control and memory to design a DTLS co-processor that can accelerate the complete DTLS state machine in hardware, thus minimizing the energy consumption due to DTLS computations. The proposed DTLS core is integrated with a RISC-V micro-processor to accurately profile these functions, as well as design custom protocols using standalone cryptographic instructions.

This book presents the different challenges of secure processor architecture design for architects working in industry who want to add security features to their designs as well as graduate students interested in research on architecture and hardware security. It educates readers about how the different challenges have been solved in the past and what are the best practices, i.e., the principles, for design of new secure processor architectures. Based on the careful review of past work by many computer architects and security researchers, readers also will come to know the five basic principles needed for secure processor architecture design. The book also presents existing research challenges and potential new research directions. Finally, it presents numerous design suggestions, as well as discussing pitfalls and fallacies that designers should avoid. With growing interest in computer security and the protection of the code and data which execute on commodity computers, the amount of hardware security features in today's processors has increased significantly over the recent years. No longer of just academic interest, security features inside processors have been embraced by industry as well, with a number of commercial secure processor architectures available today. This book gives readers insights into the principles behind the design of academic and commercial secure processor architectures. Secure processor architecture research is concerned with exploring and designing hardware features inside computer processors, features which can help protect confidentiality and integrity of the code and data executing on the processor. Unlike traditional processor architecture research that focuses on performance, efficiency, and energy as the first-order design objectives, secure processor architecture design has security as the first-order design objective (while still keeping the others as important design aspects that need to be considered).
