Robust secret key capacity for the MIMO induced source model [PDF]
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014 This paper considers the problem of distilling a secret key in a Gaussian multiple-input multiple-output (MIMO) scenario with two legitimate nodes and an eavesdropper. Focusing on the realistic case without perfect knowledge of the eavesdropper channel, and following a conservative practical approach based on the maximization of the worst case secret ...

Practical limits of the secret key-capacity for IoT physical layer security [PDF]
2016 IEEE 3rd World Forum on Internet of Things (WF-IoT), 2016 The confidentiality of communications in the Internet of Things (IoT) is critical, with cryptography being currently the most widely employed method to achieve it. Establishing cryptographically secure communication links between two transceivers requires the pre-agreement on some key, unknown to an external attacker.

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 ...

Secret key capacity for multipleaccess channel with public feedback [PDF]
2013 51st Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2013 This paper was presented at Allerton 2013. We were hoping to extend the results further, but it is clear that this is not going to happen soon. Now is as good a time as any for sharing this on arXiv.

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

Common Information and Secret Key Capacity [PDF]
IEEE Transactions on Information Theory, 2013 We study the generation of a secret key of maximum rate by a pair of terminals observing correlated sources and with the means to communicate over a noiseless public com- munication channel. Our main result establishes a structural equivalence between the generation of a maximum rate secret key and the generation of a common randomness that renders the

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
