Application Model and Implementation about Team Secrecy Encryption
Zhen Liu Zhou · Advanced engineering forum · 2012
Personal and network encryption application models nowadays are analyzed in this paper, then a team secrecy encryption application model is proposed based on practical applications. In this model, members of one team have same access authority for electronic documents, and team is the smallest unit of key distribution. Procedures of distribution, transmission and updating key are offline. This model is suitable for co-confidential application among many departments which are loose coupling. An encryption system is implemented based on this model aimed at protecting Microsoft office document.
