Two methods are developed that can be applied to generate secret keys automatically from
fading propagation channels that are reciprocal but have arbitrary (ie non Gaussian) …

Wireless communication between two nodes in a multi-path, multi-hop network does not
require that the forward transmission path and the reverse one are the same. However, if a …

There is growing interest in wireless security methods that provide strong or even perfect
secrecy by taking advantage of features of the physical propagation channel. In advantage …

Physical layer key generation that exploits reciprocity and randomness of wireless fading
channels has attracted considerable research attention in recent years. Although theoretical …

Channel gains are frequently used to obtain a secret key that can be used for encryption in
physical layer security systems. However, the channel gains captured by the nodes may not …

Physical layer security is a technique that makes use of the physical communication channel
or medium to provide additional robustness to eavesdroppers and attackers. Key …

As a promising way for establishing secret keys, physical layer key generation has been
broadly studied, which typically extracts secret keys with wireless channel characteristics …

Physical layer secret key can be extracted from wireless fading channels based on channel
quantization with guardband (CQG). In this paper, we analyze the key generation efficiency …

Secret key generation from the randomness provided by random channels is currently
considered as one way to improve security in wireless communications at the physical layer …

This letter investigates the secret key capacity of key generation from correlated wireless
channels in a source model. We systematically study a practical scenario by taking into …
