Steganographic Stream Cipher Encryption Using True Random Number Generator

J.J. Tatarkiewicz, W. Kuźmicz (RANDAEMON sp. z o.o., Poland)

A novel, computationally simple method of hiding any mes-sage in the stream of random bits by using a secret key is pre-sented, and a hardware-based true random number generator that can be used to produce a stream of random bits is de-scribed. The source of entropy in this generator is the random emission of low-energy electrons from the nuclear decay of the 63Ni isotope.
