It has been more than 20 years since the seminal publications on side-channel attacks. They aim at extracting secrets from embedded systems while they execute cryptographic algorithms, and they consist of two steps, measurement and analysis. This book tackles the analysis part, especially under situations where the targeted device is protected by random masking. The authors explain advances in the field and provide the reader with mathematical formalizations. They present all known analyses within the same notation framework, which allows the reader to rapidly understand and learn contrasting approaches. It will be useful as a graduate level introduction, also for self-study by researchers and professionals, and the examples are taken from real-world datasets.

This book offers the reader a formalization, characterization and quantification of the real threat level posed by side-channel leaks from devices implementing cryptography. It exploits the best mathematical tools for quantifying information leakage and characterizing leakage-based attacks. The two possible approaches are described in detail. This includes the optimal attack strategy that can be derived (in specific contexts) or generic bounds regarding data complexity that can be computed. The tone of this book is essentially mathematical. It aims to establish formal foundations for techniques that are otherwise used as engineering recipes in industrial laboratories or empirical intuitions for deriving security levels from practical implementations. It is a systematization of knowledge and a compilation of relevant tools relating to the practice of side-channel analysis on embedded systems. This book provides an up-to-date and improved analysis and understanding of embedded devices that conceal secrets that can be extracted by an attacker. Typical attacks involve measuring the device's power consumption or radiated electromagnetic field. As a source of noisy information, this correlates it with secrets and enabling these secrets to be retrieved. The attacker in some cases, can purchase a blank device from the same series and learn about its leakage, particularly how it relates to the secrets. This book also covers how such information can enhance hardware attacks deployed on another device. Researchers and engineers working in the field of side-channel security for embedded systems and related countermeasures as well as hardware and software engineers focused on implementing cryptographic functionalities will want to purchase this book as a reference. Advanced-level students majoring in computer science and electrical engineering will find this book valuable as a secondary textbook.

Side-channel attacks have become a very important and well-studied area in computer security. Traditionally, side-channels are unwanted byproducts of implementations that can be exploited by an attacker to reveal secret information. In this thesis, we take a different approach towards side-channels. Instead of exploiting already existing side-channels, they are inserted intentionally into designs. These intentional side-channels have the nice property of being hidden in the noise. Only their implementer can make use of them. This makes them a very interesting building block for different applications, especially since they can also be implemented very efficiently. In this thesis, techniques to build intentional side-channels for embedded software designs, RTL level hardware designs, as well as layout level hardware implementations are presented. The usefulness of these techniques is demonstrated by building efficient side-channel based software and hardware watermarks for intellectual property protection. These side-channel based watermarks can also be extended to be used as a tool to detect counterfeit ICs, another problem the embedded system industry is facing. However, intentional side-channels also have malicious applications. In this thesis, an extremely stealthy approach to build hardware Trojans is introduced. By only modifying the IC below the transistor level, meaningful hardware Trojans can be built without adding a single transistor. Such hardware Trojans are especially hard to detect with currently proposed Trojan detection mechanisms and highlight not only the fact that new Trojan detection mechanisms are needed, but also how stealthy intentional side-channels can be. Besides intentional side-channels, this thesis also examines unintentional side-channels in delay based Physically Unclonable Functions (PUFs). PUFs have emerged as an alternative to traditional cryptography and are believed to be especially well suited for counterfeit protection. They are also often believed to be more resistant to side-channel attacks than traditional cryptography. However, by combining side-channel analysis with machine learning, we demonstrate that delay based PUFs can be attacked, using both active as well as passive side-channels. The results not only raise strong doubt about the side-channel resistance and usefulness of delay based PUFs, but also show how powerful combining side-channel analysis techniques with machine learning can be in practice.

Side-Channel Analysis plays an important role in cryptology, as it represents an important class of attacks against cryptographic implementations, especially in the context of embedded systems such as hand-held mobile devices, smart cards, RFID tags, etc. These types of attacks bypass any intrinsic mathematical security of the cryptographic algorithm or protocol by exploiting observable side-effects of the execution of the cryptographic operation that may exhibit some relationship with the internal (secret) parameters in the device. Two of the main types of side-channel attacks are timing attacks or timing analysis, where the relationship between the execution time and secret parameters is exploited; and power analysis, which exploits the relationship between power consumption and the operations being executed by a processor as well as the data that these operations work with. For power analysis, two main types have been proposed: simple power analysis (SPA) which relies on direct observation on a single measurement, and differential power analysis (DPA), which uses multiple measurements combined with statistical processing to extract information from the small variations in power consumption correlated to the data. In this thesis, we propose several countermeasures to these types of attacks, with the main themes being timing analysis and SPA. In addition to these themes, one of our contributions expands upon the ideas behind SPA to present a constructive use of these techniques in the context of embedded systems debugging. In our first contribution, we present a countermeasure against timing attacks where an optimized form of idle-wait is proposed with the goal of making the observable decryption time constant for most operations while maintaining the overhead to a minimum. We show that not only we reduce the overhead in terms of execution speed, but also the computational cost of the countermeasure, which represents a considerable advantage in the context of devices relying on battery power, where reduced computations translates into lower power consumption and thus increased battery life. This is indeed one of the important themes for all of the contributions related to countermeasures to side- channel attacks. Our second and third contributions focus on power analysis; specifically, SPA. We address the issue of straightforward implementations of binary exponentiation algorithms (or scalar multiplication, in the context of elliptic curve cryptography) making a cryptographic system vulnerable to SPA. Solutions previously proposed introduce a considerable performance penalty. We propose a new method, namely Square-and-Buffered- Multiplications (SABM), that implements an SPA-resistant binary exponentiation exhibiting optimal execution time at the cost of a small amount of storage -- O(\sqrt(\ell)), where \ell is the bit length of the exponent. The technique is optimal in the sense that it adds SPA-resistance to an underlying binary exponentiation algorithm while introducing zero computational overhead. We then present several new SPA-resistant algorithms that result from a novel way of combining the SABM method with an alternative binary exponentiation algorithm where the exponent is split in two halves for simultaneous processing, showing that by combining the two techniques, we can make use of signed-digit representations of the exponent to further improve performance while maintaining SPA-resistance. We also discuss the possibility of our method being implemented in a way that a certain level of resistance against DPA may be obtained. In a related contribution, we extend these ideas used in SPA and propose a technique to non-intrusively monitor a device and trace program execution, with the intended application of assisting in the difficult task of debugging embedded systems at deployment or production stage, when standard debugging tools or auxiliary components to facilitate debugging are no longer enabled in the device. One of the important highlights of this contribution is the fact that the system works on a standard PC, capturing the power traces through the recording input of the sound card.

Embedded Systems are ubiquitous, used in various applications, ranging from low-end electronic appliances to high-end rockets. Security on such systems is a major concern where any useful insight gained by the adversary is harmful. Side Channel Attacks (SCAs) are performed by observing properties such as power usage, processing time and electro magnetic(EM) emissions, to correlate these external manifestations with internal computations. These properties are used to obtain critical information, such as a secret key of a secure application. Power analysis has been the most effective technique to extract secret keys during the execution of cryptographic algorithms using SCAs. This book elaborates on power analysis based side channel attacks detailing all the common attacks and the countermeasures proposed in the past. It also presents novel processor designs to combat against such attacks.

Although security is prevalent in PCs, wireless communications and other systems today, it is expected to become increasingly important and widespread in many embedded devices. For some time, typical embedded system designers have been dealing with tremendous challenges in performance, power, price and reliability. However now they must additionally deal with definition of security requirements, security design and implementation. Given the limited number of security engineers in the market, large background of cryptography with which these standards are based upon, and difficulty of ensuring the implementation will also be secure from attacks, security design remains a challenge. This book provides the foundations for understanding embedded security design, outlining various aspects of security in devices ranging from typical wireless devices such as PDAs through to contactless smartcards to satellites.
