摘要
Abstract
Attribute-based encryption can protect the security of users` data, but the decryption cost grows linearly with the complexity of access policy.Outsourced decryption technology makes the users only need a little overhead to decrypt and obtain the plaintext.However, a large number of decryption operations of outsourced decryption technology are dealt with by cloud service providers.But the cloud service providers are regarded as semi-trusted (honest but curious).So it is necessary to verify the correctness of outsourced decryption to ensure security for users` data.This paper proposes an efficient ABE scheme with full-verifiable outsourced decryption, it makes both the authorized users and unauthorized users can verify the correctness of the transformed ciphertext.关键词
