Abstract

We consider the problem of secret key generation from correlated Gaussian random variables in the finite blocklength regime. Such keys could be used to encrypt communication in IoT networks, and have provable secrecy guarantees in contrast to classic cryptographic approaches. We investigate the performance of polar coding schemes for generating the secret key over short blocklengths. Our simulation results show that the proposed scheme achieves close to theoretical upper bounds at short blocklengths.
