In this paper, a single antenna downlink channel with K users is analyzed in the presence of Rayleigh flat fading. A limited channel state information (CSI) feedback scheme is co...
We investigate secure communications for a four-node relayeavesdropper channel with multiple data stream transmission, assuming that the eavesdropper’s channel state information...
This work addresses the problem of information leakage of cryptographic devices, by using the reconfiguration technique allied to an RNS based arithmetic. The information leaked b...
We propose using the human body for “storing” data used in devices for the imminent ubiquitous computing era. In the future, people will use information appliances as powerful ...
In the near future, there will be increasingly powerful computers in smart cards, telephones, and other information appliances. This will create a massive infrastructure composed ...
