ABSTRACT:
A method encrypting data including selecting a pair of sequences based on a seed, performing a transposition of the data utilizing elements of a first one of the pair of sequences to produce a first transposition result, and performing a transposition of the first transposition result utilizing elements of a second one of the pair of sequences to produce the encrypted data. The pair of sequences may be selected from a pool of constrained sequences. The pool of constrained sequences may be generated utilizing a Knights Tour sequence generating system. The pool of constrained sequences may be transferred to a decrypting device for decryption of the encrypted data. The pair of sequences may be randomly generated utilizing a random integer sequence generator and the seed. The constrained indication may be constrained to a number of sequences present in the pool of sequences.
