摘要
 
We propose a general framework to design a general class of random number generators suitable for both computer simulation and computer security applications. It can include newly proposed generators SAFE (Secure And Fast Encryption) and ChaCha, a variant of Salsa, one of the four finalists of the eSTREAM ciphers. SAFE generator, proposed by Deng, Shiau, Lu and Bowman (2018), is to transform two classical linear generators as baseline generators into a highly non-linear generator via a mutual table shuffling method with some ARX (Addition, Rotation, XOR) operations on selected table entries. Salsa/ChaCha is popular counter-based stream cipher which produces a string of "secure" random numbers from a collection of sixteen 32-bit words, often viewed in a 4C 4 matrix and it utilizes a number of rounds of ARX-transformations to diffuse the successive matrix. In this talk, we propose a general procedure to utilize baseline RNGs to fill a large collection of input nodes in a network and make ARX-transformations on nodes in its successive middle layers. The nodes of the output layer will produce the set of "secure" random numbers ciphers.
