Abstract

Abstract:

Continuous-variable quantum key distribution (CVQKD) technique owns the advantages of potential high secret key rate and excellent compatibility with classical optical communication technique. It has attracted much attention and has been developed rapidly in the past decades. Now the unconditional security of theoretical Gaussian-modulated CVQKD protocol has been fully proven. However, for a practical CVQKD system, its hardware and software cannot be theoretically perfect. In one aspect, these imperfections will lower the secure secret key rate of the CVQKD system and incur security problems. In the other aspect, they can be used by Eve to implement hacking attacks to hide her intercept-resend attack without being detected by the legitimated parties. In this paper, we take a review of the worldwide development of the study on practical security of CVQKD from two aspects, i.e., the influence of imperfections of practical CVQKD system on its operational security and the concrete attacks incurred by these perfections. Moreover, a brief prospection is given for the study of practical security of CVQKD.
