对实用量子密码系统的定时攻击
Timing attacks on practical quantum cryptographic systems
摘要：
由于光子是长距离量子通信的唯一可用候选者，大多数量子密码设备在物理上实现为基于量子力学定律运行安全协议的光学系统。但是，为了最终产生可用于加密的比特流（密钥），需要量子到经典的转变。因此，这些任务中涉及的电子和光电元件的同步成为必要和重要的步骤。然而，它也打开了基于时间的漏洞和攻击的可能性。
英文摘要：
With photons being the only available candidates for long-distance quantum communication, most quantum cryptographic devices are physically realized as optical systems that operate a security protocol based on the laws of quantum mechanics. But to finally yield a stream of bits (secret key) usable for encryption, a quantum-to-classical transition is required. Synchronization of electronic & optoelectronic components involved in such tasks thus becomes a necessary and important step. However, it also opens up the possibility of timing-based loopholes and attacks.
