A function private attribute based encryption

摘要：

　　Users are inclined to share sensitive data in a remote server if strong security mechanism is in place.Searchable encryption satisfies the need of users to execute a search on encrypted data Previous schemes are vulnerable to keyword guessing attack (KGA), some work has done to prevent this attack.On Crypto 2013,Boneh.etc proposed a novel security definition, function private, for public key encryption system.It is to prevent secret key from leaking information to malicious adversary.For searchable encryption, trapdoor of searching keyword can be seen as secret key.Hence, using this technique can efficiently resistant keyword guessing attack.In this paper, we propose an attribute based encryption which is function private, then extend this scheme to a searchable attribute based encryption which keyword guessing secure.
