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

Due to the broadcast nature of wireless channels, wireless communication is vulnerable to
eavesdropping, message modification, and node impersonation. Securing the wireless …

Leveraging a wireless multipath channel as the source of common randomness, many key
generation methods have been proposed according to the information-theory security …

Recently, there has been great interest in physical layer security techniques that exploit the

This paper presents a thorough experimental study on key generation principles, ie,
temporal variation, channel reciprocity, and spatial decorrelation, through a testbed …

Key generation from the randomness of wireless channels is a promising alternative to
public key cryptography for the establishment of cryptographic keys between any two users …

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 …

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 …

Physical layer key generation (PKG) is a promising means to provide on-the-fly shared
secret keys by exploiting the intrinsic randomness of the radio channel. However, the …

When implementing data encryption and decryption in a symmetric cryptosystem, secure
distribution of the secret key to legitimate nodes can be a challenge. In this paper, we …
