Network Keys Exchange Facility (NKEF) is a kind of negotiatory protocol. With it, network user can correspond with each other in ID authentication mode, encryption styles and secure connect time. It's one of research hotspots of network security problem. In this paper, Shamir protocol based scheme for Secret Transmission of digital image is proposed. According to the exchangeable character of encrypting operator, we give the scheme, which can overcome the traditional method's disadvantages including insecurity and that the amount of key is too large. This method takes full advantage ofShamir protocol' s skillful idea.
