Secret-Key Generation from Private Identifiers under Channel Uncertainty
Vamoua Yachongka, Rémi A. Chou
This study investigates secret-key generation for device authentication using physical identifiers, such as responses from physical unclonable functions (PUFs). The system includes…
Performance Analysis of Indoor VLC Network with Secure Downlink NOMA for Body Blockage Model
Tianji Shen, Vamoua Yachongka, Yuto Hama +1
In this work, we investigate the performance of indoor visible light communication (VLC) networks based on power domain non-orthogonal multiple access (NOMA) for mobile devices, wh…
Outer Bounds on the CEO Problem with Privacy Constraints
Vamoua Yachongka, Hideki Yagi, Hideki Ochiai
We investigate the rate-distortion-leakage region of the Chief Executive Officer (CEO) problem, considering the presence of a passive eavesdropper and privacy constraints. We start…
Secret-Key Agreement Using Physical Identifiers for Degraded and Less Noisy Authentication Channels
Vamoua Yachongka, Hideki Yagi, Hideki Ochiai
Secret-key agreement based on biometric or physical identifiers is a promising security protocol for authenticating users or devices with small chips due to its lightweight securit…
Biometric Identification Systems With Both Chosen and Generated Secret Keys by Allowing Correlation
Vamoua Yachongka, Hideki Yagi
We propose a biometric identification system where the chosen- and generated-secret keys are used simultaneously, and investigate its fundamental limits from information-theoretic…
Secret Key-based Authentication With Passive Eavesdropper for Scalar Gaussian Sources
Vamoua Yachongka, Hideki Yagi, Yasutada Oohama
We analyze the fundamental trade-off of secret key-based authentication systems in the presence of an eavesdropper for correlated Gaussian sources. A complete characterization of t…
Biometric Identification Systems With Noisy Enrollment for Gaussian Source
Vamoua Yachongka, Hideki Yagi, Yasutada Oohama
In the present paper, we investigate the fundamental trade-off of identification, secrecy, storage, and privacy-leakage rates in biometric identification systems for hidden or remo…
Fundamental Limits of Biometric Identification Systems with Strong Secrecy
Vamoua Yachongka, Hideki Yagi
The fundamental limits of biometric identification systems under a strong secrecy criterion are investigated. In the previous studies of this scenario, the fundamental trade-off am…
Fundamental Limits of Identification System With Secret Binding Under Noisy Enrollment
Vamoua Yachongka, Hideki Yagi
We study the fundamental limits of biometric identification systems with chosen secret from an information theoretic perspective. Ignatenko and Willems (2015) characterized the cap…
Identification, Secrecy, Template, and Privacy-Leakage of Biometric Identification System Under Noisy Enrollment
Vamoua Yachongka, Hideki Yagi
In this study, we investigate fundamental trade-off among identification, secrecy, template, and privacy-leakage rates in biometric identification systems. Ignatenko and Willems (2…
