Title:
Secure Wire Shuffling in the Probing Model
Authors: Jean-Sebastien Coron, Lorenzo Spignoli
Abstract:In this paper we describe the first improvement of the wire shuffling countermeasure against side-channel attacks described by Ishai, Sahai and Wagner at Crypto 2003. More precisely, we show how to get worst case statistical security against t probes with running time {\mathcal O}(t) instead of {\mathcal O}(t \log t); our construction is also much simpler. Recall that the classical masking countermeasure achieves perfect security but with running time {\mathcal O}(t^2).
