Abstract
In this paper, we proposed an adaptive key generation based on the channel characteristics in OFDM mobile radio. We have shown that DCT-based preprocessing can remove the redundancy of the channel response and it also reduces the error in the key candidate. The simulation results show that the proposed adaptive key generation realizes high-level key agreement securely by combining the preprocessing and the error detecting method.
