- Abstract
In order to find an effective secret key generation scheme in wireless networks, many based on received signal strength methods have been proposed. However, the secret bit rates of existing schemes are relatively low. To resolve the problem of low generation rate, a vector quantization scheme is proposed in this paper where channel measurements are reused and every measurement can be quantified into two bits without increasing mismatching rate. Performance simulation results show that our proposed scheme improves the key generation rate almost twice at high entropy in comparison to the traditional schemes. At the same time, our scheme passes the randomness tests of the NIST test suite.
