ePrint Report: eLIMInate: a Leakage-focused ISE for Masked Implementation

Hao Cheng, Daniel Page

Even given a state-of-the-art masking scheme, masked software implementation of some cryptography functionality can pose significant challenges stemming, e.g., from simultaneous requirements for efficiency and security. In this paper we design an Instruction Set Extension (ISE) to address a specific element of said challenge, namely the elimination of micro-architectural leakage. Conceptually, the ISE allows a leakage-focused behavioural hint to be communicated from software to the micro-architecture: using …
