...The BEDBUG generator itself is a mere 5 lines of code: Three rotations; two pseudo-random lookups. The default BEDBUG configuration alternates the rotation constants unpredictably. These four sets of three values differ between BEDBUG128, BEDBUG256 and BEDBUG512 and were selected, tuned and tested in each case for optimal avalanche, which is never less than 16.5 bits.

...Reduced to essentials, MOTE is only 5 lines of code: Ten arithmetic and bitwise operations in all. It's called MOTE because a PRNG can't be made much smaller (or faster) without introducing bias or severely reducing avalanche. MOTE alternates its shift and rotation constants unpredictably, and has passed the most stringent industry-standard tests for randomness and security, including NIST & DIEHARD.

...This new sentence can then be transmitted to a remote user, and using the same software, "de-crypted" into yielding the original sentence. The software relies on having a known "seed" value for the random number generator, which is known only by the sender and receiver. It also relies on the sender and receiver having a shared (identical) vocabulary file. The project contains code to test input sentences for inclusion of words in the current vocabulary, and can create entries for new words as needed. The vocabulary has a "MD-5 hash" value to make sure that the share vocabulary file is identical for both sender and receiver. ...
