+ abstract = {In the last 10 years, cache attacks on Intel x86 CPUs have gained increasing attention among the scientific community and powerful techniques to exploit cache side channels have been developed. However, modern smartphones use one or more multi-core ARM CPUs that have a different cache organization and instruction set than Intel x86 CPUs. So far, no cross-core cache attacks have been demonstrated on non-rooted Android smartphones. In this work, we demonstrate how to solve key challenges to perform the most powerful cross-core cache attacks Prime+Probe, Flush+Reload, Evict+Reload, and Flush+Flush on non-rooted ARM-based devices without any privileges. Based on our techniques, we demonstrate covert channels that outperform state-of-the-art covert channels on Android by several orders of magnitude. Moreover, we present attacks to monitor tap and swipe events as well as keystrokes, and even derive the lengths of words entered on the touchscreen. Eventually, we are the first to attack cryptographic primitives implemented in Java. Our attacks work across CPUs and can even monitor cache activity in the ARM TrustZone from the normal world. The techniques we present can be used to attack hundreds of millions of Android devices.},

+ abstract = {The need for power- and energy-efficient computing has resulted in aggressive cooperative hardware-software energy management mechanisms on modern commodity devices. Most systems today, for example, allow software to control the frequency and voltage of the underlying hardware at a very fine granularity to extend battery life. Despite their benefits, these software-exposed energy management mechanisms pose grave security implications that have not been studied before.In this work, we present the CLKSCREW attack, a new class of fault attacks that exploit the security-obliviousness of energy management mechanisms to break security. A novel benefit for the attackers is that these fault attacks become more accessible since they can now be conducted without the need for physical access to the devices or fault injection equipment. We demonstrate CLKSCREW on commodity ARM/Android devices. We show that a malicious kernel driver (1) can extract secret cryptographic keys from Trustzone, and (2) can escalate its privileges by loading self-signed code into Trustzone. As the first work to show the security ramifications of energy management mechanisms, we urge the community to re-examine these security-oblivious designs.},

+ title = {CounterSEVeillance: Performance-Counter Attacks on AMD SEV-SNP},
+ abstract = {Confidential virtual machines (VMs) promise higher security by running the VM inside a trusted execution environment (TEE). Recent AMD server processors support confidential VMs with the SEV-SNP processor extension. SEV-SNP provides guarantees for integrity and confidentiality for confidential VMs despite running them in a shared hosting environment.In this paper, we introduce CounterSEVeillance, a new side-channel attack leaking secret-dependent control flow and operand properties from performance counter data. Our attack is the first to exploit performance counter side-channel leakage with single-instruction resolution from SEV-SNP VMs and works on fully patched systems. We systematically analyze performance counter events in SEV-SNP VMs and find that 228 are exposed to a potentially malicious hypervisor. CounterSEVeillance builds on this analysis and records performance counter traces with an instruction-level resolution by single-stepping the victim VM using APIC interrupts in combination with page faults. We match CounterSEVeillance traces against binaries, precisely recovering the outcome of any secret-dependent conditional branch and inferring operand properties. We present four attack case studies, in which we exemplarily showcase concrete exploitable leakage with 6 of the exposed performance counters. First, we use CounterSEVeillance to extract a full RSA-4096 key from a single Mbed TLS signature process in less than 8 minutes. Second, we present the first side-channel attack on TOTP verification running in an AMD SEV-SNP VM, recovering a 6-digit TOTP with only 31.1 guesses on average. Third, we show that CounterSEVeillance can leak the secret key from which the TOTPs are derived from the underlying base32 decoder. Fourth and finally, we show that CounterSEVeillance can also be used to construct a plaintext-checking oracle in a divide-and-surrender-style attack. We conclude that moving an entire VM into a setting with a privileged adversary increases the attack surface, given the vast amounts of code not vetted for this specific security setting.},

+abstract="Decentralized anonymity infrastructures are still not in wide use today. While there are technical barriers to a secure robust design, our lack of understanding of the incentives to participate in such systems remains a major roadblock. Here we explore some reasons why anonymity systems are particularly hard to deploy, enumerate the incentives to participate either as senders or also as nodes, and build a general model to describe the effects of these incentives. We then describe and justify some simplifying assumptions to make the model manageable, and compare optimal strategies for participants based on a variety of scenarios.",

As a result, each individual process step that could possibly cause violation of that relation has to be preceded by a test deciding whether the process in question is allowed to proceed or has to be delayed. The resulting design is readily—and quite systematically—implemented if the different processes can be granted mutually exclusive access to a common store in which “the current system state” is recorded.},

+abstract = {We present Tor, a circuit-based low-latency anonymous communication service. This second-generation Onion Routing system addresses limitations in the original design by adding perfect forward secrecy, congestion control, directory servers, integrity checking, configurable exit policies, and a practical design for location-hidden services via rendezvous points. Tor works on the real-world Internet, requires no special privileges or kernel modifications, requires little synchronization or coordination between nodes, and provides a reasonable tradeoff between anonymity, usability, and efficiency. We briefly describe our experiences with an international network of more than 30 nodes. We close with a list of open problems in anonymous communication.},

We propose a new trapdoor mechanism and derive from this technique three encryption schemes: a trapdoor permutation and two homomorphic probabilistic encryption schemes computationally comparable to RSA. Our cryptosystems, based on usual modular arithmetics, are provably secure under appropriate assumptions in the standard model.",

+abstract="An untraceable payments system based on an extension of public key cryptography, called blind signatures, has been presented previously by the author. The existence of such blind signature systems was not demonstrated. An actual set of implementable functions is presented in the present work which have the blind signature property, and for which the blindness of the signature is proved without any assumptions about computational infeasibility. In terms of the simple payments system previously presented, this means that even a conspiracy between the bank and payee can learn nothing from their participation in the payments protocol about the identity of the payer.",
