摘要
为提升量子密码时移攻击效果,提出了一种新型时移攻击方法。根据时移攻击的技术原理,对其具体步骤进行了分析,指出攻击可操作空间是时移攻击的重要参数,对比了已有的两类时移攻击方法。在此基础上,提出了新型时移攻击的基本流程与具体方法,并对实际参数进行了求解。计算结果表明,该方法可以显著扩展攻击可操作空间并降低时移攻击被发现的概率。
To promote the effect of time-shift attack in quantum cryptography, a new-type time-shift attack is put forward. Based on the technical rationale, the concrete steps of time-shift attack are analyzed. It is pointed out that the operational space is an important parameter of attack. And, two known time-shift attack methods are compared with each other. Based on that, the procedure and steps of the new-type time-shift attack are provided and actual parameters are solved. The calculation results are presented to prove that the new-type time-shift attack can significantly expand the operational space and reduce the chances that this attack is exposed.
