Quantum-secure covert communication on bosonic channels.
Computational encryption, information-theoretic secrecy and quantum cryptography offer progressively stronger security against unauthorized decoding of messages contained in communication transmissions. However, these approaches do not ensure stealth--that the mere presence of message-bearing transmissions be undetectable. We characterize the ultimate limit of how much data can be reliably and ...
متن کاملStudy on Airspace Covert Communication Algorithm of Covert Communication System
Based on the security of information transmission through network in the information society, the paper puts forward covert communication technology which is more reliable than the prior encryption algorithm, analyzes channel covertness and information hiding of covert communication technology based on spread-spectrum communication technology, and establishes a covert communication system inclu...
متن کاملCovert Communication through Executables
This paper explores the potential of executables for covert communication. Three techniques for the embedding of secret information are presented. Possible attacks on the stealthiness of these techniques are identified and countered. The presented concepts are implemented and evaluated for the IA32 architecture, for which we obtain an encoding rate of 1/27 before countermeasures and 1/89 after ...
متن کاملBehavioral Mimicry Covert Communication
Covert communication refers to the process of communicating data through a channel that is neither designed, nor intended to transfer information. Traditionally, covert channels are considered as security threats in computer systems and a great deal of attention has been given to countermeasures for covert communication schemes. The evolution of computer networks led the communication community...
