ABSTRACT:
A method, apparatus, and system of encryption, including embedding reconfiguration information within a ciphertext block destined for a decryptor. The decryptor identifies the reconfiguration information, extracts such information, and uses it to alter a pre-cipher, which is used for decryption. The encryptor alters its pre-cipher synchronously with the decryptor.
