Abstract:
A method is provided for processing a digital information set having a plurality of information bytes. The method comprises receiving the information set, determining a set of initialization parameters, initializing a set of state variables using the set of initialization parameters, and generating a plurality of cryptors, each cryptor being a virtual dynamic array containing a monoalphabetic cipher. The method further comprises modifying the state variables and one or more of the cryptors, setting the index value for each cryptor in the plurality of cryptors; and selecting an ordered cryptor subset to be applied to an information byte. The information byte is processed using the ordered cryptor subset to produce a processed information byte. If the information byte is a plaintext byte, the processed byte is an encrypted byte, and vice versa. The actions of modifying, setting, selecting, and processing are then repeated for each remaining information byte.
