On the design and quantification of privacy preserving data mining algorithms
Dakshi Agrawal,Charu C. Aggarwal +1 more
TL;DR: It is proved that the EM algorithm converges to the maximum likelihood estimate of the original distribution based on the perturbed data, and proposed metrics for quantification and measurement of privacy-preserving data mining algorithms are proposed.
Book ChapterDOI
The EM Side-Channel(s)
TL;DR: It is shown that not only can EM emanations be used to attack cryptographic devices where the power side-channel is unavailable, they can even beused to break power analysis countermeasures.
Proceedings ArticleDOI
Trojan Detection using IC Fingerprinting
TL;DR: These results show that Trojans that are 3-4 orders of magnitude smaller than the main circuit can be detected by signal processing techniques and provide a starting point to address this important problem.
Proceedings ArticleDOI
Space-time coded OFDM for high data-rate wireless communication over wideband channels
TL;DR: A space-time coded orthogonal frequency division multiplexing (OFDM) modulated physical layer is designed which combines coding and modulation and is attractive for delay-sensitive applications.
Journal ArticleDOI
Multiple-antenna signal constellations for fading channels
TL;DR: A numerical optimization procedure for finding good packings in the complex Grassmannian space is described and the best signal constellations found by this procedure improve significantly upon previously known results.
