Abstract: An important problem in public clouds is how to selectively share documents based on fine-grained attribute-based access control policies. An approach is to encrypt documents satisfying different policies with different keys using a public-key cryptosystem such as attribute-based encryption (ABE), and/or proxy re-encryption (PRE). However, such an approach has some weaknesses: it cannot efficiently handle adding/revoking users or identity attributes, and policy changes; it requires keeping multiple encrypted copies of the same documents; it incurs high computational costs. A direct application of asymmetric key cryptosystem, where users are grouped based on the policies they satisfy and assigning unique keys for each group, also has similar weaknesses. Without utilizing public-key cryptography and by allowing users to dynamically derive the symmetric keys at the time of decryption, one can address the above weaknesses. Based on this idea, a new key management scheme called broadcast group key management (BGKM) is proposed and then gives a secure construction of a BGKM scheme called ACVBGKM. The idea is to give some secrets to users based on the identity attributes they have and later allow them to derive actual symmetric keys based on their secrets and some public information. A key advantage of the BGKM scheme is that adding users/revoking users or updating access control policies can be performed efficiently by updating only some public information.
Keywords: searchable encryption, fine-grained search, authorization, dynamic access policy.
