摘要：Quantum cryptography, also known as Quantum Key distribution (QKD), distributes secret random bit between two remote parties Alice and Bob. In the presence of an eavesdropper, Eve, whose power is only limited by the laws of physics, QKD can still provide information-theoretic security in theory. However, in practice, the behaviors of implementations in QKD may not act exactly same as the theoretical models in security proofs. Such deviations can lead to security loopholes in practice and enable an eavesdropper to launch so-called side channel attacks and to break the security totally in practical QKD devices.

In this presentation Hao Qin will talk about his research activities in the quantum hacking lab （www.vad1.com）.  Particularly, he will briefly introduce several quantum hacking attacks that have been recently reported by his group, which include the most famous attack: blinding attack, spatial mode mismatch attack, single photon detector back flash attack, laser damage attack, Trojan horse attack etc. Hao Qin will also discuss possible countermeasures against these attacks and efforts of his group in certification standards for quantum communication technology.
