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…
