| Abstract(in English) | One of the criteria of security of Identity-based encryption is anonymity. The anonymity is defined using a game between an adversary and a challenger. The ANO-LOR-ATK model is defined anonymity definition. Proposed the ANO-SW-ATK model, the ANO-ROR-ATK model and the ANO-PR-ATK model in ISEC 2016-71, and we clarified the relationship between the ANO-LOR-ATK security and the ANO-SW-ATK security in the case of CCA2. In addition consider about the ANO-ROR-ATK model and the ANO-PR-ATK model. |
