Random number generation methods are subjected to numerous researches in various fields such as cryptography. In this research, statistical quality of a few million digits of binary expansion of some irrational numbers has been tested through dozen of standard tests developed for random and pseudorandom number generators. The results indicate that digits of binary expansion of these numbers can be...
In this paper, an efficient MPEG video encryption scheme is presented by employing chaotic cipher. In order to provide video content protection, first, selective encryption is completed by encrypting Fixed Length Codeword (FLC), using proposed chaotic stream cipher. Then, for each frame, macro block shuffling is executed in video bit stream, using chaos-based permutation. The proposed chaotic cryptographic...
We define the class of trapdoor pseudo-random number generators, and introduce a new technique for using these in cryptography. As an application for this technique, we present a provably secure protocol for One-Bit Disclosures i.e. for giving a one-bit message in exchange for receipt.
