拦截攻击

抵抗多次拦截攻击的量子密钥分发中的身份认证

Identity Verification in Quantum Key Distribution for Resisting Attack of Multi-Time Interceptions

不惜任何代价的拦截攻击！

Intercept and attack at any cost !

依据这些信息，对攻击行为执行缓冲区边界检查，栈边界检查，返回地址保护和跳转指令检查，在缓冲区溢出攻击流程的关键节点拦截攻击，增强系统运行过程中的安全性。

Based on these information , make the attack code accepts the buffer boundary check , stack boundary check , return address check and jump instruction check , intercept attacks on the key nodes of buffer overflow attacks , enhance system dynamic security .

报告称，2017年上半年，腾讯的智能手机杀毒软件拦截病毒攻击6.93亿次，同比增长124.24%，二维码成为这些病毒的主要来源之一，占比达20.8%。

Tencent 's anti-virus program for smartphones prevented 693 million attempted virus attacks in the first half of 2017 , an increase of 124.24 % year-on-year , and QR codes were a major source of those viruses , accounting for 20.8 % , the report said .

不仅服役用于训练用途，JJ-7也可以被用来空中拦截和对地攻击任务。

As well as serving for training purpose , the JJ-7 could also be used for air interception and ground attack roles .

给出的量子身份认证协议中引入了基于时间参数和认证密钥的伪随机序列，使攻击者进行的拦截次数只有达到时间参数长度的指数级，才能获得同一粒子的副本，逃避了多次拦截攻击。

Based on the pseudorandom bit generator with time parameters and the verification keys , the identity verification protocol in quantum key distribution proposed can avoid the attack because the attacker has to intercept exponential times in the length of time parameters to obtain just one copy of a particle .
