We propose a Success Rate (SR) estimation model for Correlation Power Analysis (CPA) attack on AES-128 encrypted devices. The SR is a ratio between the number of successful attacks to obtain secret key and the total number of attacks. There are two key features in the proposed model. First, we derive the Second Order Standard Deviation (SOSD) of the processed data to analyze their switching activities...
A huge limitation of the correlation analysis in existing scatterer model is that the former model, only consisting of uniformly distributed scatterers, ignores the variability of complex scattering intensity in real situation. In fact, each part of the target has a different scattering architecture. Moreover, the scattering intensity of pinnacle or boundary scattering structure is an order of magnitude...
In this paper, an automatic audio commercial recognition based on coarse-to-fine matching strategy is proposed. First, to index audio commercials in the database efficiently, the locality sensitive hash (LSH) is applied to accelerating the initial retrieval procedure. Second, with respect to the collision occurred in the initial LSH matching, a fine matching procedure based on Fine Granularity Successive...
