PROJECT TITLE :

Secure Source Coding With Action-Dependent Side Information

ABSTRACT:

We tend to consider the problems of secure lossy source coding with side data in the presence of a passive eavesdropper who has access to the source description. The encoder needs to compress the supply sequence in order to satisfy a distortion criterion at the decoder, while revealing only limited knowledge regarding the supply to the eavesdropper. The facet info on the market to the encoder, the legitimate decoder, or the eavesdropper will be influenced by a price-constrained action sequence. 3 different settings are studied. In the first 2 settings, we are fascinated by understanding the influence of the action sequence on the speed-distortion-leakage tradeoff where the action is taken either by the decoder or by the encoder to influence aspect data at the decoder and eavesdropper. Next, we have a tendency to consider a setting where common action-dependent side data is available securely to both encoder and decoder, and therefore will be used for secret key generation. We have a tendency to characterize the optimal rate-distortion-value-leakage region or the corresponding inner bounds for a discrete memoryless source for above settings. The results are useful in characterizing elementary limits for instance in secure sensor networking and future cyber physical systems.
