\begin{frame}{What is a Tamper Sensing Mesh?}
|
||||||
|
\begin{itemize}
|
||||||
|
\item Embedded looped conductor covering a surface
|
||||||
|
\item Detects physical intrusion
|
||||||
|
\begin{itemize}
|
||||||
|
\item Drills, saws, lasers etc.
|
||||||
|
\end{itemize}
|
||||||
|
\item Triggers some tamper response
|
||||||
|
\begin{itemize}
|
||||||
|
\item Deleting keys
|
||||||
|
\item Raising alarms
|
||||||
|
\item Explosions?
|
||||||
|
\end{itemize}
|
||||||
|
\item Widely used in HSMs, payment terminals, ATMs, nuclear weapons

\begin{frame}{The History of Tamper-Sensing Meshes}
|
||||||
|
\begin{itemize}
|
||||||
|
\item \textbf{1870}: First patents using literal wire meshes to protect bank vaults~\cite{ImprovementProtectingSafes1870,ImprovementElectromagneticEnvelopes1870}
|
||||||
|
\item \textbf{1902}: Multi-layer, orthogonal meshes documented~\cite{suttonElectricallyprotectedStructure1902}
|
||||||
|
\item \textbf{1971}: Printed circuit technology adopted~\cite{hamPrintedcircuitTypeSecurity1971}
|
||||||
|
\item \textbf{1990s}: Widespread commercial adoption with cryptographic applications
|
||||||
|
\end{itemize}
|
||||||
|
|
||||||
|
Other, hard to date examples: NSA use for protecting ciphering machines~\cite{boakHistoryUSCommunications1973,boakHistoryUSCommunications1981}, US use in nuclear weapons~\cite{carterManagingNuclearOperations1987}

\begin{frame}{Commercial Applications Today}
|
||||||
|
\begin{itemize}
|
||||||
|
\item Datacenter HSMs (Key management, payment processing)
|
||||||
|
\item Card Payment Terminals (PIN encryption)
|
||||||
|
\item ATM Encrypting Pin Pads (PIN encryption)
|
||||||
|
\item Key Safes for Emergency services access (Germany only?)
|
||||||
|
\item Mail Franking Machines (credit counter)
|
||||||
|
\item Slot Machines (likely for DRM)

\begin{frame}{Security Issues Observed}
|
||||||
|
\begin{itemize}
|
||||||
|
\item Incomplete mesh coverage
|
||||||
|
\item Meshes not overlapping at edges leaving gaps for probe insertion
|
||||||
|
\item Gaps at mesh-PCB interfaces
|
||||||
|
\item Thermoformed cavities with enlarged structure size at corners
|
||||||
|
\item In one case, an opaque lacquer was easily removed with acetone (without damaging the mesh!)
|
||||||
|
\item Trace patterns visible through cover layers due to surface unevenness
|
||||||
|
\end{itemize}

\begin{frame}{Design Recommendations (1/2)}
|
||||||
|
\begin{itemize}
|
||||||
|
\item Commodity PCB manufacturing process design rules in the \SIrange{100}{200}{\micro\meter} range are better than the state of the art in mesh structure size
|
||||||
|
\item Avoid ink printing processes or thermoforming because of their large structure size
|
||||||
|
\item Carefully think about your literal corner cases (and edges)!
|
||||||
|
\begin{itemize}
|
||||||
|
\item Overlap meshes where possible.
|
||||||
|
\end{itemize}
|
||||||
|
\item Use potting and cover layers, but verify that they work
|
||||||
|
\begin{itemize}
|
||||||
|
\item Check that you \emph{actually} can't see what's below
|
||||||
|
\item Test their chemical resistance (and that of your mesh)
|
||||||
|
\end{itemize}
|
||||||
|
\end{itemize}
|
||||||
|
\end{frame}
|
||||||
|
|
||||||
|
\begin{frame}{Design Recommendations (2/2)}
|
||||||
|
\begin{itemize}
|
||||||
|
\item Mixing tough potting or enclosure materials and fragile mesh materials makes life harder for an attacker
|
||||||
|
\begin{itemize}
|
||||||
|
\item Consider using steel instead of plastic (also helps against X-ray inspection!)
|
||||||
|
\item Use thin substrates and thin conductive layers for the mesh
|
||||||
|
\item Balance adhesion so removing potting / cover layers tears away traces below
|
||||||
|
\end{itemize}
|
||||||
|
\item Overlap mesh layers at a 50\% structure size offset
|
||||||
|
\item Space (some) mesh layers apart in Z direction to constrain attack tools
|
||||||
|
\item Use a pressure-sensitive connection method like tactile domes or elastomeric conncetors
|
||||||
|
\end{itemize}

Focusing on the writings of Timothy May and Julian Assange, two of the most prolific and influential cypherpunks, the book examines two competing paradigms of cypherpunk philosophy—crypto anarchy and crypto justice—and examines the implications of cypherpunk ethics for a range of contemporary moral issues, including surveillance, privacy, whistleblowing, cryptocurrencies, journalism, democracy, censorship, intellectual property, and power. Rooted in theory but with very real applications, this volume will appeal not only to students and scholars of digital media, communication, journalism, philosophy, political science, critical data studies, sociology, and the history of technology but also to technologists and activists around the world.},

abstract = {Germany is currently rolling out an opt-out, nation-scale database of the medical records of the majority of~its population, with low-income people being disproportionally represented among its users. While there has~been considerable criticism of the system coming from civil society, independent academic analysis of the system by~the cryptography and information security community has been largely absent. In this paper, we aim to raise awareness~of the system’s existence and, based on the system’s public specifications, highlight several concerning cryptographic engineering decisions. Our core observations is that the system’s most sensitive long-term user keys are derived~by a rudimentary, home-grown centralized key escrow mechanism. This mechanism relies on a per-use salt and only 256~bit of entropy, shared globally across millions of users. Furthermore, the system’s specification mandates only level~3 compliance with the obsolete FIPS 140-2 security standard, which requires “hard, opaque potting”, but lacks active tamper sensing. As a result, the system remains vulnerable to attacks by nation states and other well-funded adversaries.},

abstract = {The crypto wars have raged for half a century. In the 1970s, digital privacy activists prophesied the emergence of an Orwellian State, made possible by computer-mediated mass surveillance. The antidote: digital encryption. The U.S. government warned encryption would not only prevent surveillance of law-abiding citizens, but of criminals, terrorists, and foreign spies, ushering in a rival dystopian future. Both parties fought to defend the citizenry from what they believed the most perilous threats. The government tried to control encryption to preserve its surveillance capabilities; privacy activists armed citizens with cryptographic tools and challenged encryption regulations in the courts. No clear victor has emerged from the crypto wars. Governments have failed to forge a framework to govern the, at times conflicting, civil liberties of privacy and security in the digital age—an age when such liberties have an outsized influence on the citizen–State power balance. Solving this problem is more urgent than ever. Digital privacy will be one of the most important factors in how we architect twenty-first century societies—its management is paramount to our stewardship of democracy for future generations. We must elevate the quality of debate on cryptography, on how we govern security and privacy in our technology-infused world. Failure to end the crypto wars will result in societies sleepwalking into a future where the citizen–State power balance is determined by a twentieth-century status quo unfit for this century, endangering both our privacy and security. This book provides a history of the crypto wars, with the hope its chronicling sets a foundation for peace.},

However, encryption schemes are generally not directly compatible with user passwords and thus, Password-Based Key Derivation Functions (PBKDFs) are used to convert user passwords into cryptographic keys. In this paper, we analyze the theoretical security of PBKDF2 and present two vulnerabilities, γ-collision and δ-collision. Using AES-128 as our exemplar, we show that due to γ-collision, text encrypted with one user password can be decrypted with γ − 1 different passwords. We also provide a proof that finding a collision in the derived key for AES-128 requires δ lesser calls to PBKDF2 than the known Birthday attack. Due to this, it is possible to break password-based AES-128 in O(264) calls, which is equivalent to brute-forcing DES.},

abstract = {Due to its sound theoretical basis and practical efficiency, masking has become the most prominent countermeasure to protect cryptographic implementations against physical sidechannel attacks (SCAs). The core idea of masking is to randomly split every sensitive intermediate variable during computation into at least t+1 shares, where t denotes the maximum number of shares that are allowed to be observed by an adversary without learning any sensitive information. In other words, it is assumed that the adversary is bounded either by the possessed number of probes (e.g., microprobe needles) or by the order of statistical analyses while conducting higher-order SCA attacks (e.g., differential power analysis). Such bounded models are employed to prove the SCA security of the corresponding implementations. Consequently, it is believed that given a sufficiently large number of shares, the vast majority of known SCA attacks are mitigated. In this work, we present a novel laser-assisted SCA technique, called Laser Logic State Imaging (LLSI), which offers an unlimited number of contactless probes, and therefore, violates the probing security model assumption. This technique enables us to take snapshots of hardware implementations, i.e., extract the logical state of all registers at any arbitrary clock cycle with a single measurement. To validate this, we mount our attack on masked AES hardware implementations and practically demonstrate the extraction of the full-length key in two different scenarios. First, we assume that the location of the registers (key and/or state) is known, and hence, their content can be directly read by a single snapshot. Second, we consider an implementation with unknown register locations, where we make use of multiple snapshots and a SAT solver to reveal the secrets.},

The core idea of masking is to randomly split every sensitive intermediate variable during computation into at least t+1 shares, where t denotes the maximum number of shares that are allowed to be observed by an adversary without learning any sensitive information. In other words, it is assumed that the adversary is bounded either by the possessed number of probes (e.g., microprobe needles) or by the order of statistical analyses while conducting higher-order SCA attacks (e.g., differential power analysis). Such bounded models are employed to prove the SCA security of the corresponding implementations. Consequently, it is believed that given a sufficiently large number of shares, the vast majority of known SCA attacks are mitigated. In this work, we present a novel laser-assisted SCA technique, called Laser Logic State Imaging (LLSI), which offers an unlimited number of contactless probes, and therefore, violates the probing security model assumption. This technique enables us to take snapshots of hardware implementations, i.e., extract the logical state of all registers at any arbitrary clock cycle with a single measurement. To validate this, we mount our attack on masked AES hardware implementations and practically demonstrate the extraction of the full-length key in two different scenarios. First, we assume that the location of the registers (key and/or state) is known, and hence, their content can be directly read by a single snapshot. Second, we consider an implementation with unknown register locations, where we make use of multiple snapshots and a SAT solver to reveal the secrets.},

abstract = {Quantum key distribution using weak coherent states and homodyne detection is a promising candidate for practical quantum-cryptographic implementations due to its compatibility with existing telecom equipment and high detection efficiencies. However, despite the actual simplicity of the protocol, the security analysis of this method is rather involved compared to discrete-variable QKD. In this article we review the theoretical foundations of continuous-variable quantum key distribution (CV-QKD) with Gaussian modulation and rederive the essential relations from scratch in a pedagogical way. The aim of this paper is to be as comprehensive and self-contained as possible in order to be well intelligible even for readers with little pre-knowledge on the subject. Although the present article is a theoretical discussion of CV-QKD, its focus lies on practical implementations, taking into account various kinds of hardware imperfections and suggesting practical methods to perform the security analysis subsequent to the key exchange.

abstract = {The threats of physical side-channel attacks and their countermeasures have been widely researched. Most physical side-channel attacks rely on the unavoidable influence of computation or storage on current consumption or voltage drop on a chip. Such data-dependent influence can be exploited by, for instance, power or electromagnetic analysis. In this work, we introduce a novel non-invasive physical side-channel attack, which exploits the data-dependent changes in the impedance of the chip. Our attack relies on the fact that the temporarily stored contents in registers alter the physical characteristics of the circuit, which results in changes in the die's impedance. To sense such impedance variations, we deploy a well-known RF/microwave method called scattering parameter analysis, in which we inject sine wave signals with high frequencies into the system's power distribution network (PDN) and measure the echo of the signals. We demonstrate that according to the content bits and physical location of a register, the reflected signal is modulated differently at various frequency points enabling the simultaneous and independent probing of individual registers. Such side-channel leakage challenges the t-probing security model assumption used in masking, which is a prominent side-channel countermeasure. To validate our claims, we mount non-profiled and profiled impedance analysis attacks on hardware implementations of unprotected and high-order masked AES. We show that in the case of the profiled attack, only a single trace is required to recover the secret key. Finally, we discuss how a specific class of hiding countermeasures might be effective against impedance leakage.},

abstract = {Most terminal devices authenticate users only once at the time of initial login, leaving the terminal unprotected during an active session when the original user leaves it unattended. To address this issue, continuous authentication has been proposed by automatically locking the terminal after a period of inactivity. However, it does not fully eliminate the risk of unauthorized access before the session expires. Recent research has also investigated the feasibility of using physiological and behavioral patterns as biometrics. This study presents a novel two-factor continuous authentication that explores a new form of signal called human-induced electric potential captured by wearables in contact with the user’s body. By analyzing this signal, we can determine the time of user-terminal interactions and compare it with information recorded by the terminal’s OS. If the original user remains on the same terminal, the two-source readings would match. Additionally, the proposed scheme includes an extra layer of protection by extracting terminal’s physical fingerprints from the human-induced electric potential to defend against advanced mimicry attacks. To test the effectiveness of our design, a low-cost wearable prototype is developed. Through extensive experiments, it is found that the proposed scheme has a low error rate of 2.3\%, with minimal computational and energy requirements.},

abstract = {Privacy issue is a main concern restricting data sharing and cross-organization collaborations. While Privacy-Preserving Machine Learning techniques such as Multi-Party Computations (MPC), Homomorphic Encryption, and Federated Learning are proposed to solve this problem, no solution exists with both strong security and high performance to run large-scale, complex machine learning models. This paper presents PPMLAC, a novel chipset architecture to accelerate MPC, which combines MPC's strong security and hardware's high performance, eliminates the communication bottleneck from MPC, and achieves several orders of magnitudes speed up over software-based MPC. It is carefully designed to only rely on a minimum set of simple hardware components in the trusted domain, thus is robust against side-channel attacks and malicious adversaries. Our FPGA prototype can run mainstream large-scale ML models like ResNet in near real-time under a practical network environment with non-negligible latency, which is impossible for existing MPC solutions.},
