Relative dimension/length profile (RDLP), inverse relative dimension/length profile (IRDLP) and relative length/dimension profile (RLDP) are equivalent sequences of a linear code and a subcode. The concepts were applied to protect messages from an adversary in the wiretap channel of type II with illegitimate parties. The equivocation to the adversary is described by IRDLP and upper-bounded by t...

Consider a wireless communication system in which Alice wishes to transmit a message to Bob in the presence of an eavesdropper, Eve. We consider the design of a communication technique that allows Alice to send a message such that Bob can decode it but Eve can get little information about the message. This scenario is a classic example of the wiretap channel, for which several researchers have ...

In this paper we consider the State-Dependent Wiretap Channel (SD-WC). As the main idea, we model the SD-WC as a Cognitive Interference Channel (CIC), in which the primary receiver acts as an eavesdropper for the cognitive transmitter’s message. By this point of view, the Channel State Information (CSI) in SD-WC plays the role of the primary user’s message in CIC which can be decoded at the eav...

In this paper, bounds to the secrecy capacity region for the general 3-receiver broadcast channel with 3 degraded message sets, are presented for confidential messages sent to be kept secret from one of the receivers. This model is a more general model than 2-receiver broadcast channels with confidential messages with an external wiretapper, and recently studied 3-receiver degraded broadcast ch...

Finite-length codes are learned for the Gaussian wiretap channel in an end-to-end manner assuming that communication parties equipped with deep neural networks (DNNs), and communicate through binary phase-shift keying (BPSK) modulation scheme. The goal is to find via DNNs which allow a pair of transmitter receiver reliably securely presence adversary aiming at decoding secret messages. Followin...

Abstract Two striking claims are advanced on behalf of the free energy principle (FEP) in cognitive science and philosophy: (i) that it identifies a condition possibility existence for self-organising systems; (ii) has important implications our understanding how brain works, defining set process theories—roughly, theories structure functions neural mechanisms—consistent with minimising imperat...

To a cryptographer the claim that “Shannon Security was achieved with keys smaller than the encrypted message" appears unworthy of attention, much as the claim of “perpetuum mobile” is to a physicist. Albeit, from an engineering point of view solar cells which power satellites exhibit an “essential perpetuum mobile” and are of great interest. Similarly for Shannon Security, as it is explored in...
