量子密码中密钥的直接使用

Direct Use of Secret Key in Quantum Cryptography

Horace P. Yuen

摘要:

对于两个用户之间的单光子量子密钥生成,它表明,通过伪随机数发生器扩展的共享密钥的使用可以同时提高密码系统的安全性和效率。这种效应是由具有密钥知识的量子检测器与不具有密钥知识的量子检测器之间的固有性能差异、纯粹的量子效应和用于密钥生成的新原理引起的。该方法不需要入侵级别估计,可直接应用于具有缺陷的实际系统。量子直接加密也可以通过使用密钥来实现。

英文摘要:

For single-photon quantum key generation between two users, it is shown that the use of a shared secret key extended via a pseudo-random number generator may simultaneously enhance the security and efficiency of the cryptosystem. This effect arises from the intrinsic performance difference between quantum detectors with versus without knowledge of the key, a purely quantum effect and a new principle for key generation. No intrusion level estimation is needed and the method is directly applicable to realistic systems with imperfections. Quantum direct encryption is also made possible by such use of a secret key.
