摘要

Microarchitectural side channel attacks have been very prominent in security research over the last few years. Caches proved to be an outstanding side channel, as they provide high resolution and generic cross-core leakage. All major cryptographic libraries provide countermeasures to hinder key extraction via cross-core cache attacks by now. In this paper, we analyze implementations protected by p...
