Streszczenie

W artykule przedstawiono metodę wyznaczania charakterystyki pojemności informacyjnej termograficznego kanału komunikacji skrytej zbudowanego z promiennika ciepła (technicznego ciała czarnego) oraz kamery termowizyjnej. Wyznaczone charakterystyki stanowią dodatkowy parametr opisujący te urządzenia w kontekście ich nieoczywistego zastosowania do transmisji danych.

Characterization of Thermographic Covert Channel

Abstract

The paper presents a method for determining the characteristics of the information capacity of a thermographic covert communication channel made of a heat radiator (technical black body) and a thermal camera. The determined characteristics are an additional parameter describing these devices in the context of their non-obvious use for data transmission.

Keywords

channel capacity, steganography, termography
