Existing personal and network encryption application modes are summarized, and a new kind of offline team confidential document application mode is defined and analyzed for satisfying special confidential demand in practical. In this mode, confidential electronic documents are classified by team’s role. Team is the smallest unit of key distribution, and access authority is allowed to be delivered between teams. PKI system dependable on Intranet or Internet is forbidden to use in this mode. In response, a cross-access method based on offline key management for this new mode is proposed, algorithms for authorization, encryption, authentication, and decryption in this method are described in detail through an implement example of transparent encryption system using Microsoft Office plug-in technology.
