Software-based Microarchitectural Attacks
Modern processors are highly optimized systems where every single cycle of computation time matters. Many optimizations depend on the data that is being processed. Software-based microarchitectural attacks exploit effects of these optimizations. Microarchitectural side-channel attacks leak secrets from cryptographic computations, from general purpose computations, or from the kernel. This leaka...
متن کاملMicroarchitectural Attacks and Countermeasures
Microarchitectural analysis (MA) is a fast evolving area of side-channel cryptanalysis. This new area focuses on the effects of common processor components and their functionalities on the security of software cryptosystems. The main characteristic of microarchitectural attacks, which sets them aside from classical side-channel attacks, is the simple fact that they exploit the microarchitectura...
متن کاملMASCAT: Stopping Microarchitectural Attacks Before Execution
Microarchitectural attacks have gained popularity in recent years since they use only standard resources, e.g. memory and cache access timing. Such privileges are available to applications at the lowest privilege levels. Further, microarchitectural attacks have proven successful on shared cloud instances across VMs, on smartphones with sandboxing, and on numerous embedded platforms. Given the r...
متن کاملSurvey of Microarchitectural Side and Covert Channels, Attacks, and Defenses
Over last two decades, side and covert channel research has shown variety of ways of exfiltrating information for a computer system. Processor microarchitectural side and covert channel attacks have emerged as some of the most clever attacks, and ones which are difficult to deal with, without impacting system performance. Unlike electromagnetic or power-based channels, microarchitectural side a...
متن کاملTitle: Advances in Side-Channel Cryptanalysis: MicroArchitectural Attacks
approved: Çetin Kaya Koç Cryptographic devices leak timing and power consumption information that is easily measurable, radiation of various levels, and more. Such devices also have additional inputs, other than plaintext and keys, like voltage, which can be modified to force the device to produce certain faulty outputs that can be used to reveal the secret key. Side-channel cryptanalysis uses ...
