Abstract
We proposed a new public key encryption scheme with equality test (PKEET), which stands for a public key encryption scheme with comparable ciphertext. The equivalence among ciphertext under PKEET schemes can be verified without decryption. In some PKEET algorithms like Tang’s AoN-PKEET, which is called authorization-based PKEET, the equality test functionality is restricted to some authorized users: only users who own authorities are able to perform equality test functions. For the best of our knowledge, the authorities of all existing authorization-based PKEET schemes are valid for all ciphertext encrypted under the same public key. Accurately, we propose a CBA-PKEET scheme following Tang’s AoN-PKEET scheme, which means a PKEET scheme with ciphertext-binded authorities (CBA). Each ciphertext-binded authority is valid for a specific ciphertext, rather than all ciphertext encrypted under the same public key. Then, we compare the features and efficiency between our CBA-PKEET and some existing authorization-based PKEET schemes. Finally, the security of CBA-PKEET is proved in the random oracle model based on the some hard problems.
