Abstract
A new cryptographic technique is disclosed, called decoy bits method, which can be used to obtain near ideal information theoretic security in both quantum and classical key generation and data encryption, not only for raw security but also under known-plaintext attacks. The technique relates to a method of data encryption by insertion of random bits, called decoy bits, into a data sequence whereby the decoy bits are discarded upon decryption. The positions of the decoy bits are determined by a decoy position determining mechanism. This method can be used in conjunction with other standards of encryption to increase security.
