Y-00在快速相关等密钥攻击下的安全性

On the Security of Y-00 under Fast Correlation and Other Attacks on the Key

Horace P. Yuen, Ranjith Nair

摘要:

在S. Donnet等人在Phys.Lett. A 35,6(2006)406 - 410.在本文中,我们将展示如何可以消除这个弱点,一个适当的设计ENC。特别是,我们提出了一个Y-00配置,是更安全的比AES下已知明文攻击。研究还表明,在任何纯密文攻击下,当采用适当的故意信号随机化时,对于任何ENC,Y-00种子密钥都是完全信息论安全的。

英文摘要:

The potential weakness of the Y-00 direct encryption protocol when the encryption box ENC in Y-00 is not chosen properly is demonstrated in a fast correlation attack by S. Donnet et al in Phys. Lett. A 35, 6 (2006) 406-410. In this paper, we show how this weakness can be eliminated with a proper design of ENC. In particular, we present a Y-00 configuration that is more secure than AES under known-plaintext attack. It is also shown that under any ciphertext-only attack, full information-theoretic security on the Y-00 seed key is obtained for any ENC when proper deliberate signal randomization is employed.
