BASICS is a simple encryption scheme (with authentication) based on permutations and dynamic substitutions of characters.
In order that the encryption operations involved could be most easily understood by the common users, the scheme highly closely follows the simple and popularly known classical schemes of transposition and substitution but which nonetheless, due to the high dynamics realized via corresponding computer programming means, are strong enough to resist attacks of the adversary with modern analysis resources.
