Side-channel Attacks and Countermeasures for the MK-3 Authenticated Encryption Scheme
"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.
Hardware Security Training, Hands-on!
This is the first book dedicated to hands-on hardware security training. It includes a number of modules to demonstrate attacks on hardware devices and to assess the efficacy of the countermeasure techniques. This book aims to provide a holistic hands-on training to upper-level undergraduate engineering students, graduate students, security researchers, practitioners, and industry professionals, including design engineers, security engineers, system architects, and chief security officers. All the hands-on experiments presented in this book can be implemented on readily available Field Programmable Gate Array (FPGA) development boards, making it easy for academic and industry professionals to replicate the modules at low cost. This book enables readers to gain experiences on side-channel attacks, fault-injection attacks, optical probing attack, PUF, TRNGs, odometer, hardware Trojan insertion and detection, logic locking insertion and assessment, and more.
