Abstract
The key reconciliation stage in the secret key generation process may leak partial information to the eavesdropper through the public channel. In this thesis, two metrics, based on rate-distortion and entropy are considered to gauge the secrecy achievable with a channel scheme with side information at the receivers. Two theorems that provide bounds on the performance in this scenario according to different metrics are considered, and the resulting performance in terms of secret key rate is assessed.| File | Dimensione | Formato | |
