Several security models of multiple-access channel (MAC) are investigated. First, we study the degraded MAC with confidential messages, where two users transmit their confidential messages (no common message) to a destination, and each user obtains a degraded version of the output of the MAC. Each user views the other user as a eavesdropper, and wishes to keep its confidential message as secret...

We revisit the problems of state masking and amplification through lens empirical coordination. Specifically, we characterize rate-equivocation-coordination trade-offs regions a state-dependent channel in which encoder has causal strictly knowledge. also extend this characterization to cases two-sided information noisy feedback. Our approach is based on notion core receiver’s knowledge, introdu...

The paper provides an information theoretic account for similarity-based concept learning. It shows that the process can be understood as the attempt to minimise both the information content and equivocation (noise) of inputs from the environment.

The force and the deceptive nature of the fallacy of equivocation lies in its dialectical nature. The speaker redefines a word in order to classify a fragment of reality, while the hearer draws a conclusion based on the ordinary meaning of such a classification. This difference between the interlocutors’ meanings is grounded on a crucial epistemic gap: how is it possible to know our hearer’s mi...

We propose a new concept of secure list decoding, which is related to bit-string commitment. While the conventional decoding requires that contains transmitted message, following additional security conditions work as modification The first condition receiver’s uncertainty for stronger than impossibility correct even though message contained in list. other sender estimate another element decode...

Using concepts drawn from semiotic, the general theory of signs, and from the mathematical theory of communication, a theoretical framework is developed within which the problems relating to communication system adaptation may be defined and models of such adaptation constructed. The relationship between the semiotical notions of qualisign and legisign is used to define a concept of tolerance s...

Transmission of classical information over a quantum state-dependent channel is considered, when the encoder can measure side (CSI) and required to mask on state from decoder. In this setting, it essential conceal CSI measurement as well. A regularized formula derived for masking equivocation region, full characterization established class channels.
