Wireless Information-Theoretic Security
TLDR
A practical secure communication protocol is developed, which uses a four-step procedure to ensure wireless information-theoretic security and is shown that the protocol is effective in secure key renewal-even in the presence of imperfect channel state information.Abstract:
This paper considers the transmission of confidential data over wireless channels. Based on an information-theoretic formulation of the problem, in which two legitimates partners communicate over a quasi-static fading channel and an eavesdropper observes their transmissions through a second independent quasi-static fading channel, the important role of fading is characterized in terms of average secure communication rates and outage probability. Based on the insights from this analysis, a practical secure communication protocol is developed, which uses a four-step procedure to ensure wireless information-theoretic security: (i) common randomness via opportunistic transmission, (ii) message reconciliation, (iii) common key generation via privacy amplification, and (iv) message protection with a secret key. A reconciliation procedure based on multilevel coding and optimized low-density parity-check (LDPC) codes is introduced, which allows to achieve communication rates close to the fundamental security limits in several relevant instances. Finally, a set of metrics for assessing average secure key generation rates is established, and it is shown that the protocol is effective in secure key renewal-even in the presence of imperfect channel state information.read more

Remote State Estimation over Packet Dropping Links in the Presence of an Eavesdropper.
TL;DR: Structural results on the optimal transmission policy are derived, and shown to exhibit thresholding behavior in the estimation error covariances, and it is shown that with unstable systems one can keep the expected estimation error covariance bounded while the expected eavesdroppererror covariance becomes unbounded.
