Security Enhancement of Quantum Noise Stream Cipher Based on Probabilistic Constellation Shaping (W2B.33)
Presenter: Sheng Liu, China Mobile Research Institute
We propose a QNSC pre-coding scheme based on probabilistic shaping of the basis, to reduce the probability of ciphertext bits that are easier to be intercepted. Experiment results show this scheme can improve the security performance by 100% in terms of Eve’s cipher text BER.
