| Summary: | The security and privacy issues in SNS were studied and a privacy-preserving scheme PPSNS was proposed. PPSNS utilizes attribute-based encryption, allowing the SNS user to set up an enforcement of fine-grained access control upon the data he owns, thus the potential threats from unauthorized parties or even the SNS provider itself could be avoided. A token system in PPSNS is included to address the challenging issue of efficient attribute revocation. In addi-tion, the users in PPSNS don't have to manage as much information as they do in other encryption-based solutions, achieving a much lower cost in the client side. Analyses show that PPSNS is secure, and gives a better performance in computing and storage costs compared to most related works. |
