Predicting Secret Keys Via Branch Prediction
This paper announces a new software side-channel attack — enabled by the branch prediction capability common to all modern highperformance CPUs. The penalty paid (extra clock cyc...

VPC prediction: reducing the cost of indirect branches via hardware-based dynamic devirtualization
Indirect branches have become increasingly common in modular programs written in modern object-oriented languages and virtualmachine based runtime systems. Unfortunately, the pred...

New Branch Prediction Vulnerabilities in OpenSSL and Necessary Software Countermeasures
Abstract. Software based side-channel attacks allow an unprivileged spy process to extract secret information from a victim (cryptosystem) process by exploiting some indirect leaka...

Reducing Branch Costs via Branch Alignment
Several researchers have proposed algorithms for basic block reordering. We call these branch alignment algorithms. The primary emphasis of these algorithms has been on improving ...
