Abstract

The security of the Y-00 direct encryption protocol under correlation attack is addressed. A Y-00 configuration that is more secure than AES under known-plaintext attack is presented. It is shown that under any ciphertext-only attack, full information-theoretic security on the Y-00 seed key is obtained for any encryption box ENC with proper deliberate signal randomization.
