Secret Key Generation With Multiantenna Relays
IEEE Access, 2023 One effective way of generating and distributing secret keys for secure communication is to exploit the randomness of wireless channels. Since a potential eavesdropper has a different propagation channel than two legitimate users, it can be used to ...

Intelligent Reflecting Surface–Assisted Wireless Secret Key Generation against Multiple Eavesdroppers [PDF]
Entropy, 2022 In this paper, we propose an improved physical layer key generation scheme that can maximize the secret key capacity by deploying intelligent reflecting surface (IRS) near the legitimate user aiming at improving its signal-to-noise ratio (SNR).

Attack Algorithm for a Keystore-Based Secret Key Generation Method [PDF]
Entropy, 2019 A new attack algorithm is proposed for a secure key generation and management method introduced by Yang and Wu. It was previously claimed that the key generation method of Yang and Wu using a keystore seed was information-theoretically secure and could ...

Secret Key Generation Between Ambient Backscatter Devices
IEEE Access, 2023 We analyze secret key generation between ambient backscatter devices where the channel between an ambient transmitter and the backscatter devices is used as a source of randomness.

A Simple Secret Key Generation by Using a Combination of Pre-Processing Method with a Multilevel Quantization [PDF]
Entropy, 2019 Limitations of the computational and energy capabilities of IoT devices provide new challenges in securing communication between devices. Physical layer security (PHYSEC) is one of the solutions that can be used to solve the communication security ...

Covert Secret Key Generation With an Active Warden
IEEE Transactions on Information Forensics and Security, 2020 We investigate the problem of covert and secret key generation over a state-dependent discrete memoryless channel with one-way public discussion in which an adversary, the warden, may arbitrarily choose the channel state. We develop an adaptive protocol that, under conditions that we explicitly specify, not only allows the transmitter and the ...
