Query: A Fast Pseudo-Stochastic Sequential Cipher Generator Based on RBMs   Based on Restricted Boltzmann Machines (RBMs), an improved pseudo-stochastic
sequential cipher generator is proposed. It is effective and efficient because
of the two advantages: this generator includes a stochastic neural network that
can perform the calculation in parallel, that is to say, all elements are
calculated simultaneously; unlimited number of sequential ciphers can be
generated simultaneously for multiple encryption schemas. The periodicity and
the correlation of the output sequential ciphers meet the requirements for the
design of encrypting sequential data. In the experiment, the generated
sequential cipher is used to encrypt the image, and better performance is
achieved in terms of the key space analysis, the correlation analysis, the
sensitivity analysis and the differential attack. The experimental result is
promising that could promote the development of image protection in computer
security.
