Security is a crucial issue in distributed applications of multihop wireless opportunistic network due to the features exposed on fly communication, relaxed end-to-end connectivity, and vague destinations literately. In this paper, we focus problems user privacy leakage confidentiality invasion content-based or interest-centric network. And propose public-encryption-with-fuzzy-keyword-search- (PEFKS-) ciphertext-policy-attribute-based-encryption- (CP-ABE-) based security scheme by refining compromising two-pairing-based encryption, searchable attribute-based encryption. Our enables forwarding according fuzzy interests preserving full users ensures with fine-grained access control strategy an scenario large-scale networks. Finally, analyze evaluate terms performance.
