METHOD AND APPARATUS FOR AUTOKEY ROTOR ENCRYPTION |
摘要 |
A method an apparatus for block or stream encrypting text uses an autokeyed rotational state vector to encrypt plain text to yield cipher text. The text is stored as a block in a buffer of an arbitrary number of bytes. Each byte of plain text in the buffer encrypted to yield a byte of cipher text by using a rotational state vector, and the rotational state vector is updated or changed as a function of one or more of: the cipher text, the plain text and a key. The encryption operation is advantageously a series of alternating non-linear and linear transformations. The method of encryption is advantageously involutory in that the encryption method and apparatus for a given key is identical to the decryption method and apparatus with the same key.
