Abstract

To overcome various problems of QKD, postquantum cryptography (PQC), and physical-layer security (PLS) encryption protocols, in our recent paper we have proposed to employ the atmospheric turbulent channel as the source of randomness in a source type PLS cryptosystem. However, a long coherence time of atmospheric turbulence channels limits the secret-key rates (SKRs). In this invited paper, we describe an encryption scheme that overcomes the problem of the long coherence time of the turbulent channel. The proposed scheme has security better than PQC and is comparable to QKD but enables significantly higher SKRs.
