Abstract(in English) In this paper, we extract and study the basic scheme about the shared attribute certification in consideration of user's privacy protection that the entity, which certificates user's identity, does not have all of the user's information. That is, we show a basic model of shared attribute certification, which introduce shared attribute authorities and the modules called user assistant. In this model, the shared authorities manage the user's attribute information by using secret sharing schemes, and the user assistants, which can select the range about the user's attribute information for generating the attribute credentials. In addition, we propose a basic protocol of shared attribute certification.
