Fault Attack revealing Secret Keys of Exponentiation Algorithms from Branch Prediction Misses
Fault attacks branch misses performance counters
2016/1/6
Performance monitors are provided in modern day computers for observing various features of the underlying microarchitectures. However the combination of underlying micro-architectural features and pe...
Countermeasures for the Simple Branch Prediction Analysis
Simple Branch Prediction key bits modern superscalar processors
2009/1/9
Branch Prediction Analysis has been proposed as an attack method
to obtain key bits from a cryptographic application. In this report, we
put forth several solutions to avoid or prevent this attack. ...

Branch Prediction Analysis Countermeasures Modular Exponentiation
2008/12/23
Very recently, a new software side-channel attack, called Branch Prediction Analysis
(BPA) attack, has been discovered and also demonstrated to be practically feasible on popular
commodity PC platfo...
Predicting Secret Keys via Branch Prediction
Branch Prediction Modular Exponentiation Montgomery Multiplication
2008/12/15
This paper presents a new software side-channel attack enabled by the branch
prediction capability common to all modern high-performance CPUs. The penalty payed (extra
clock cycles) for a mispredict...
