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

1)量子密碼術中可能發(fā)生哪些攻擊？

Possible Attacks in Quantum Cryptography and Birthday Attack

量子密碼術和生日攻擊的可能攻擊

Birthday attack and Boomerang attack

生日襲擊和回旋鏢襲擊

Brute force attack and Faked-State-Attack

蠻力攻擊和偽造國家攻擊

Possible Attacks in Quantum Cryptography and Faked-State Attack

量子密碼術中的可能攻擊和偽造態(tài)攻擊

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

答案： d。 量子密碼術中的可能攻擊和偽造態(tài)攻擊

Explanation:

說明：

Photon Number Splitting (PNS) Attack:

光子數分裂(PNS)攻擊：

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.

眾所周知，不可能發(fā)送單個光子，因此會發(fā)送脈沖。 因此，脈沖中的一些光子可以被Eve捕獲，并且在Amit和Bobby匹配位后，Eve可以使用與Bobby相同的偏振器，從而獲得密鑰而無需在加密中被檢測到。

Faked-State Attack:

偽造狀態(tài)攻擊：

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的光子檢測器的副本，從而捕獲打算用于Bobby的光子，并將其進一步傳遞給Bobby。 因此，夏娃知道編碼位，鮑比認為他是從阿米特那里收到的。
