Covert communication based on subliminal channel in elliptic curve digital signature algorithm
Zhanhui Sun · Journal of Computer Applications · 2010
There are narrowband and broadband subliminal channels in the Elliptic Curve Digital Signature Algorithm(ECDSA),but broadband subliminal channel cannot be safely used.Therefore,the real-time test of narrowband subliminal channel was done.The reasonable bit rate of the sent message was confirmed when the capacity and real-time requests of narrowband subliminal channel were satisfied.The result shows narrowband subliminal channel can be effectively used in ECDSA.
