Profiled Model Based Power Simulator for Side Channel Evaluation

An embedded cryptographic device performs operation on sensitive data and as such, is vulnerable to side-channel attacks. This forces smart-card manufacturers to carefully consider development of security mechanisms. To accelerate this procedure, the use of power and electromagnetic simulator can be relevant and saves non negligible time. Based on a high level simulator, we propose to use profiled abstract models to gain accuracy on the simulated traces. These abstract models are obtained by profiling some parts of the target device which is physically available by the evaluator. keyword: Smart Cards, Power Simulation, Side Channel Analysis, Security Evaluation.
