A lot of devices which are daily used (i.e., credit card, pay-tv card, e-passport) have to guarantee the retention of sensible data. Sensible data are ciphered by a secure key by which only the key holder can get the data. For this reason, to protect the cipher key against possible attacks becomes a main issue. Many research activities have been directed in developing countermeasures to enhance the device resistance against attacks and, on the other side, many contributions aimed to enhance the attack itself have been reported in the technical literature. This book is a collection of the main results of a PhD in hardware cryptography about side-channel attacks and countermeasures in the design of secure IC's devices. About hardware countermeasures against power analysis, three new logic families for cryptographic applications are designed. With respect to the contributions aimed to enhance the attack methodologies, an active circuit which promises to improve the power attacks is proposed. Besides, a new side channel and a novel methodology to attack cryptographic circuits is studied. Finally, two activities focused on Random Numbers Generators are briefly described.

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.

"In the field of cryptography, the focus is often placed on security in a mathematical or information-theoretic sense; for example, cipher security is typically evaluated by the difficulty of deducing the plaintext from the ciphertext without knowledge of the key. However, once these cryptographic schemes are implemented in electronic devices, another class of attack presents itself. Side-channel attacks take advantage of the side effects of performing a computation, such as power consumption or electromagnetic emissions, to extract information outside of normal means. In particular, these side-channels can reveal parts of the internal state of a computation. This is important because intermediate values occurring during computation are typically considered implementation details, invisible to a potential attacker. If this information is revealed, then the assumptions of a non-side-channel-aware security analysis based only on inputs and outputs will no longer hold, potentially enabling an attack. This work tests the effectiveness of power-based side-channel attacks against MK-3, a customizable authenticated encryption scheme developed in a collaboration between RIT and L3Harris Technologies. Using an FPGA platform, Correlation Power Analysis (CPA) is performed on several different implementations of the algorithm to evaluate their resistance to power side-channel attacks. This method does not allow the key to be recovered directly; instead, an equivalent 512-bit intermediate state value is targeted. By applying two sequential stages of analysis, a total of between 216 and 322 bits are recovered, dependent on customization parameters. If a 128-bit key is used, then this technique has no benefit to an attacker over brute-forcing the key itself; however, in the case of a 256-bit key, CPA may provide up to a 66-bit advantage. In order to completely defend MK-3 against this type of attack, several potential countermeasures are discussed at the implementation, design, and overall system levels."--Abstract.

Side-channel attacks are attacks that make use of peripheral information, e.g., timing, power, etc, to infer private information. Recent studies have shown that attackers can learn sensitive information (e.g., cryptographic keys) through side channels, which jeopardizes the user’s security and privacy. In this work, we aim to 1) study the recent advances of side-channel attacks on modern platforms (e.g., smartphones), 2) propose mitigation mechanisms to close the network side channels. In particular, to study the side-channel attack vectors on smartphones, first, we present a systematic study of Flush-Reload side-channel attacks on ARM processors and show that the attacks can be constructed in a return-oriented fashion. We also demonstrate practical attacks on Android systems. Second, we present the first exploration of OS-level side channels on iOS, which are side channels exposed by public APIs. We show three categories of side-channel attacks on iOS to demonstrate that iOS is also vulnerable to such attacks. Our proposed mitigations have been integrated into the recent versions of iOS/MacOS. Besides investigating the attack vectors, we also propose defense mechanisms to defeat network side-channel attacks. We show how to adopt adversarial machine learning and differential privacy to defeat streaming traffic analysis attackers.

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 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.
