Cryptography plays a vital role in digital communications, working to ensure the privacy and integrity of the users and their data. However, in the last decade, attacks have emerged that target physical implementations of cryptographic algorithms. In particular, side-channel attacks are of concern. It is the task of the hardware engineer to ensure that implementations of these algorithms do not introduce weaknesses in the form of side-channel information, that could compromise the integrity of the cryptosystem. This thesis investigates side-channel attacks on FPGA implementations of cryptographic algorithms. The vulnerability of cryptographic hash functions to side-channel attacks is not usually considered in the literature. However, in protocols such as HMAC, hash functions are used to process secret key information, which can be recovered via a side-channel attack. Here, using a commercial FPGA, the vulnerability of the SHA-2 and Whirlpool hash functions to Differential Power Analysis (DPA) is proven. In response to such vulnerability, masking is a common DPA countermeasure used in academia and industry. New masking schemes are presented for both hash functions, and a novel method of converting from Boolean to arithmetic masks is developed. Secure logic styles ensure that the cryptographic device consumes a constant amount of power in each clock cycle, and represent a general countermeasure to side-channel attacks. The Double Wave Dynamic Differential Logic (DWDDL) secure logic style for FPGAs is examined, and leveraged to develop an alternative logic style, Isolated WDDL (IWDDL). Using laboratory experiments, a flaw in the DWDDL design flow is highlighted, and rectified. Another general side-channel attack countermeasure is proposed in the form of All-or-Nothing Transforms (AONTs). In this thesis, it is shown that All-or-Nothing Encryption and Decryption are inherently resistant to DPA attacks. This resistance is then further increased using a novel extension to the AONE protocol. Various AONT constructions are considered, and the performance of these schemes is analysed. The thesis concludes with a comparison of general side-channel attack countermeasures, to determine the most effective method of protecting cryptosystems against side-channel at-tacks. It is shown that a ryptosystem using the All-or-Nothing countermeasure can match the performance of (and, in certain cases, outperform) an unprotected implementation.

Power Analysis Attacks pose serious threats to hardware implementations of cryptographic systems. To retrieve the secret key, the attackers can exploit the mutual information between power consumption and processed data / operations through monitoring the power consumption of the cryptosystems. Field Programmable Gate Arrays (FPGA) have emerged as attractive implementation platforms for providing hardware-like performance and software-like flexibility for cryptosystem developers. These features come at the expense of larger power consumption, which makes FPGAs more vulnerable to power attacks. Different countermeasures have been introduced in the literature, but as they have originally been developed for Application-Specific Integrated Circuits (ASIC), mapping them onto FPGAs degrades their effectiveness. In this work, we propose a logic family based on pass transistors, which essentially consists of hardware replication, that can be used to build FPGAs with constant power consumption. Since the power consumption is no longer related to processed data and operations, a quadruple robustness to attacks based on dynamic power consumption, static power consumption, glitches, and early evaluation effect is achieved. Such a secured-by-design FPGA will relieve the cryptosystems developers from doing advanced analog design to secure the cryptosystem implementation. Our pass-transistor logic family can also be used in implementing ASICs. The silicon area overhead costs are shown to be less than prior art, which makes our FPGA attractive to cryptosystems developers.

In Security Trends for FPGA's the authors present an analysis of current threats against embedded systems and especially FPGAs. They discuss about requirements according to the FIPS standard in order to build a secure system. This point is of paramount importance as it guarantees the level of security of a system. Also highlighted are current vulnerabilities of FPGAs at all the levels of the security pyramid. It is essential from a design point of view to be aware of all the levels in order to provide a comprehensive solution. The strength of a system is defined by its weakest point; there is no reason to enhance other protection means, if the weakest point remains untreated. Many severe attacks have considered this weakness in order not to face brute force attack complexity. Several solutions are proposed in Security Trends for FPGA's especially at the logical, architecture and system levels in order to provide a global solution.

This thesis deals with side channel attacks against hardware implementations of cryptographic algorithms. Studies conducted in this document are therefore in place where an adversary has access to noisy observations of intermediate results of a cryptographic computation. In this context, many attacks are dedicated with their countermeasures, but their relevance and their implementation are still unclear. This thesis initially focuses on the relevance of existing attacks and potential links between them. A formal classification is proposed as well as selection criteria. Based on this study, a generic efficient attack is described and analyzed in depth. In a second step, the implementation of common countermeasures is studied, leading to the creation of an application scheme mixing them to achieve a better efficiency / security trade off.

On any advanced integrated circuit or "system-on-chip" there is a need for security. In many applications the actual implementation has become the weakest link in security rather than the algorithms or protocols. The purpose of the book is to give the integrated circuits and systems designer an insight into the basics of security and cryptography from the implementation point of view. As a designer of integrated circuits and systems it is important to know both the state-of-the-art attacks as well as the countermeasures. Optimizing for security is different from optimizations for speed, area, or power consumption. It is therefore difficult to attain the delicate balance between the extra cost of security measures and the added benefits.

Power analysis attacks allow the extraction of secret information from smart cards. Smart cards are used in many applications including banking, mobile communications, pay TV, and electronic signatures. In all these applications, the security of the smart cards is of crucial importance. Power Analysis Attacks: Revealing the Secrets of Smart Cards is the first comprehensive treatment of power analysis attacks and countermeasures. Based on the principle that the only way to defend against power analysis attacks is to understand them, this book explains how power analysis attacks work. Using many examples, it discusses simple and differential power analysis as well as advanced techniques like template attacks. Furthermore, the authors provide an extensive discussion of countermeasures like shuffling, masking, and DPA-resistant logic styles. By analyzing the pros and cons of the different countermeasures, this volume allows practitioners to decide how to protect smart cards.

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.
