Verifiable and Authenticated Searchable Encryption Scheme with Aggregate Key in Cloud Storage |
Abstract | ||
|---|---|---|
Searchable encryption ensures that data user can search over encrypted data stored by data owner's in cloud. However, since the cloud server is semi-trusted, it may tamper information that stored by data owners. In order to obtain data owner's information, the unauthorized users can send search requests to the cloud sercer, and it may return search results to the unauthorized users, which may lead to the leakage of information. Moreover, since different documents are encrypted with different secret keys, it is impractical for data users to search over massive documents. Aiming at these problems, we propose a searchable encryption scheme that supports verification and authentication with aggregate key. In the proposed scheme, data user interacts with the cloud server to obtain information, and uses these information to verify the integrity of ciphertexts. The cloud server can authenticate the legality of data user by authenticating whether data user's identity is contained in the authorized users' identity set. Data owner sends an aggregate key to the authorized users so as to share search permissions on his documents selectively. Finally, security and performance analysis show that the scheme is secure and efficient. |
