Our main contribution is the determination of SK-capacity for an arbitrary subset of terminals with the remaining terminals serving as \"helpers,\" when an eavesdropper observes the communication between the terminals but does not have access to any other information. We also determine the private key (PK)-capacity when the eavesdropper additionally wiretaps some of the helper terminals from which too the key must then be concealed.","PeriodicalId":92129,"journal":{"name":"Proceedings.

The predictability of the channel is characterized through the rank Q (1 /spl les/ Q /spl les/ N) of the correlation matrix of the vector of channel gains over the block. The model includes the standard block fading model and the i.i.d. fading model as special cases. For large SNR, we prove that the capacity grows logarithmically with SNR with a slope of N-Q/N (for 1 /spl les/ Q /spl les/ N). For fixed SNR and Q, we show that the capacity approaches the coherent channel capacity when N/spl rarr//spl infin/. We also characterize the asymptotics of the capacity in the regime where both N and Q/spl rarr//spl infin/, with Q/N being kept constant. The results of the paper can be generalized to include multiple antennas and frequency-selectivity.","PeriodicalId":92129,"journal":{"name":"Proceedings.
