Abstract
Technologies are generally described for providing rapid data encryption and decryption for secure communication over an open channel with plausible deniability. In some examples, a single bit of information may be encoded by many alternative combinations of bits thus providing high security as well as enabling a single ciphertext to encrypt several different plaintexts of the same length simultaneously. The ability to encrypt several different plaintexts of the same length simultaneously may allow plausible deniability of messages. Encryption speed may be enhanced through accumulation of useful bit sets with desired properties in advance for later use. When the need arises, several plaintexts of the same size may be encrypted into a single ciphertext using accumulated bit combinations corresponding to different secret keys.
