As a countermeasure for eavesdroppers in wireless communication, a secret key agreement scheme using a variable directional antenna named ESPAR antenna was developed. In this paper, we describe an improved key generation method using multi-level quantization and parity check in the secret key agreement scheme. It enhances key agreement probability in legitimate parties efficiently without reducing...
Schemes for secret key agreement based on the radio transmission path characteristics between authorized stations have been proposed as anti-eavesdropping measures in land mobile radio. In this paper, we propose a new scheme for secret key agreement. It compares the strengths of the signals received at two antennas to produce a bit of the keys. It does not use a threshold which is used in the conventional...
The purpose of this study is to evaluate a handset MIMO antenna under practical use conditions, involving multipath radio wave propagation and the influence of the body of the user. To this end, a Monte Carlo computer simulation has been carried out to investigate the distribution of eigenvalues and channel capacity
