The invention relates to an encrypted access control method under CCN (Content Centric Networking). Broadcast encryption is adopted for encrypting data packets, so that a condition that different requesters can decrypt the same authorized content can be ensured. Data encryption effectively protects privacy of a content publisher. At the same time, the encrypted data sent by the content publisher is firstly stored in a router. A requester acquires a content mark number after authorization verification by the content publisher and then the requester performs Hash operation on a requested contentname and the content mark number. Only when an obtained Hash value is identical to that sent by the content publisher in the router, the router sends the encrypted data to the requester. The authorized requester can obtain the data packets after acquiring the request content mark number and performing Hash value calculation and after the router confirms the matching success. A requester authorized to access a part of the content cannot acquire content buffering other unknown content mark numbers.
