Countermeasures for the Simple Branch Prediction Analysis

Giovanni Agosta and Gerardo Pelosi

Abstract: 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. The reported countermeasures require only minimal hardware support that is commonly available in modern superscalar processors.
