1) Which possible Attacks in Quantum Cryptography can take place?

1)量子密码术中可能发生哪些攻击？

1. Possible Attacks in Quantum Cryptography and Birthday Attack

   量子密码术和生日攻击的可能攻击

2. Birthday attack and Boomerang attack

   生日袭击和回旋镖袭击

3. Brute force attack and Faked-State-Attack

   蛮力攻击和伪造国家攻击

4. Possible Attacks in Quantum Cryptography and Faked-State Attack

   量子密码术中的可能攻击和伪造态攻击

Answer: d. Possible Attacks in Quantum Cryptography and Faked-State Attack

答案： d。 量子密码术中的可能攻击和伪造态攻击

Explanation:

说明：

Photon Number Splitting (PNS) Attack:

光子数分裂(PNS)攻击：

As we know that it is not possible to send a single photon thus a pulse is sent. So, some of the photons from a pulse can be captured by Eve and after matching bits by Amit and Bobby, Eve can use the same polarizer as done by Bobby and thus get the key without being detected in cryptography.

众所周知，不可能发送单个光子，因此会发送脉冲。 因此，脉冲中的一些光子可以被Eve捕获，并且在Amit和Bobby匹配位后，Eve可以使用与Bobby相同的偏振器，从而获得密钥而无需在加密中被检测到。

Faked-State Attack:

伪造状态攻击：

Mainly, Eve uses a replica of Bob’s photon detector and thus captures the photons intended for Bobby and further passed it to Bobby. Thus, Eve knows about the encoded bit, Bobby thinks that he received it from Amit.

Eve主要使用Bob的光子检测器的副本，从而捕获打算用于Bobby的光子，并将其进一步传递给Bobby。 因此，夏娃知道编码位，鲍比认为他是从阿米特那里收到的。
