Abstract
Cloud computing provides dynamically scalable resources provisioned as a service over networks. But untrustworthy Cloud Service Provider(CSP) offers a big obstacle for the adoption of the cloud service since CSP can access data in Cloud without data owner's permission. Hierarchical Inner Product Encryption (HIPE) covers all applications of anonymous encryption, fully private communication and search on encrypted data, which provide trusted data access control policy to CSP. However, the existing works only achieve either selectively attribute-hiding or adaptively attribute-hiding under some strong assumptions in the public key setting. To overcome them, a novel HIPE in private key setting is issued. The new scheme achieves both fully secure and security reduction under the natural assumption-Decisional Linear (DLIN) assumption in the standard model.
