Analysis of Cache Attacks and Countermeasures on the ρ-­VEX Processor

Modern implementations of encryption algorithms on CPU’s that use frequent memory lookups of precomputed functions, are vulnerable to Cache based Side­Channel Attacks. The ρ­-VEX processor, a runtime reconfigurable VLIW processor developed at the Computer and Quantum Engineering department at the TU Delft was identified to possibly allow for...

Exploitation of Cache Based Side-Channels on ARM: Correlation Analysis of Access-driven Cache Attacks on Android Smartphones

Android smartphones collect and compile a huge amount of sensitive information which is secured using cryptography. There is an unintended leakage of information during the physical implementation of a cryptosystem on a device. Such a leakage is often termed as side channel and is used to break the implementation of cryptographic algorithms. In...
