The Secret Key Capacity of a Class of Noisy Channels with Correlated Sources [PDF]
Entropy, 2019 This paper investigates the problem of secret key generation over a wiretap channel when the terminals observe correlated sources. These sources are independent of the main channel and the users overhear them before the transmission takes place.

IEEE AccessSteganography hides a secret message inside another medium (cover-image) while maintaining imperceptibility and/or robustness/embedding capacity, making it a suitable candidate for keeping information safe and hiding the existence of data itself inside ...

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).

Secrecy Capacity Region of the AWGN MAC with External Eavesdropper and Feedback
Entropy, 2023 For the point-to-point additive white Gaussian noise (AWGN) channel with an eavesdropper and feedback, it has already been shown that the secrecy capacity can be achieved by a secret key-based feedback scheme, where the channel feedback is used for ...

Biometric Identification Systems with Noisy Enrollment for Gaussian Sources and Channels
Entropy, 2021 In the present paper, we investigate the fundamental trade-off of identification, secret-key, storage, and privacy-leakage rates in biometric identification systems for remote or hidden Gaussian sources. We use a technique of converting the system to one

A Secure Data Hiding For H.264 Video Based on Chaotic Map Methods and RC4 Algorithm
Iraqi Journal of Information & Communication Technology, 2023 Video steganography is the common field of data security in digital communication where data include text, image, and video. Compressed video is the suitable modern source for hiding huge secret data that will trust security.

Secure Secret Key and Private Key Generation in Source-Type Model With a Trusted Helper
IEEE Access, 2020 Encrypting information with pre-agreed key is an effective method to ensure information security. With the increasing requirement for key rate, this paper investigates the problem of simultaneously generating a secret key (SK) and a private key (PK) over

An Efficient Advantage Distillation Scheme for Bidirectional Secret-Key Agreement
Entropy, 2017 The classical secret-key agreement (SKA) scheme includes three phases: (a) advantage distillation (AD), (b) reconciliation, and (c) privacy amplification.
