Recently,measurement-device-independent quantum secure direct communication schemes were proposed by Niu et al.[Sci.Bull.63 1345(2018)]and Zhou et al.[Sci.China-Phys.Mech.Astron.63 230362(2020)].Inspired by their ideas,in this paper,a measurement-device-independent quantum dialogue protocol based on entanglement is designed and proven to be secure.The advantage of this scheme is that it can not only allow two communicators to transmit secret messages between each other,making the application scenarios more extensive,but can also eliminate all the security loopholes related to the measurement device and information leakage.In terms of experimental implementation,the scheme mainly involves the preparation of entangled states,the preparation of single photons,quantum storage,Bell measurement and other technologies,all of which are mature at present,therefore,the scheme is feasible by using current technologies.
