Security analysis of measurement-device-independent quantum key distribution under electromagnetic leakage attack

This paper presents an effective attack targeting the transmitters of the MDI-QKD system by exploiting leaked EM signals and shows that a convolutional neural network can recover the modulation information with an accuracy of over 97%.

Performance evaluation of twin-field quantum key distribution with injection-type attacks.

This work investigates the security of the NPP TF-QKD protocol in the presence of imperfect intensity modulation, focusing on Trojan-horse attacks and induced photorefractive attacks, and establishes a finite-key security proof that explicitly incorporates this source-side information leakage.
