Threshold Constraints on Symmetric Key Extraction from Rician Fading Estimates
IEEE Transactions on Mobile Computing
Symmetric key establishment using reciprocal quantization of channel estimates in wireless Rician fading environments is considered. The quantization bits from channel-phase and channel-amplitude are treated as the output of a random number generator. We determine threshold constraints on the required minimal distance of the legitimate communicating parties from a passive eavesdropper, and determine threshold constraints on maximal key establishing rates. The analysis makes use of widelydoi:10.1109/tmc.2012.226 fatcat:6vyqubasmvhojlz7lww3g73kwm
