英文摘要	Today's online social networking services (OSN) such as Facebook, Twitter are centralized. Users' information may be leaked by these service providers, which results in potential privacy problems. Decentralized online social networking (DOSN) is provided to solve the problems. This paper presents a secure decentralized online social networking framework named SEDOSN. A peer-to-peer (p2p) online networking system is designed, and attribute-based encryption (ABE) technique is used. Different to existing ABE schemes which relies on a single authority or several authorities to authorize users and generating decryption keys for uses, we firstly proposed an ABE scheme with discretionary authorization. In our system, each user can authorize his friend, and generate decryption keys for his friend based on his friend's attributes. We give our implementation and experiment results in the paper.; EI; CPCI-S(ISTP); fangyj@ss.pku.edu.cn; zlwen@pku.edu.cn; qingnishen@ss.pku.edu.cn; yhyang@ss.pku.edu.cn; wuzh@pku.edu.cn; 68-74; 572
