METHOD AND APPARATUS FOR PROVIDING ENCRYPTION/DECRYPTION USING TWO SEQUENCES OF NUMBERS

摘要

A method encrypting data including selecting a pair of séquences based on a seed, performing a transposition of the data utilizing éléments of a first one of the pair of séquences to produce a first transposition resuit, and performing a transposition of the first transposition resuit utilizing éléments of a second one of the pair of séquences to produce the encrypted data. The pair of séquences may be selected from a pool of constrained séquences. The pool of constrained séquences may be generated utilizing a Knights Tour séquence generating System. The pool of constrained séquences may be transferred to a decrypting device for decryption of the encrypted data. The pair of séquences may be randomly generated utilizing a random integer séquence generator and the seed. The constrained indication may be constrained to a number of séquences présent in the pool of séquences.
