摘要: 摘 要: 传统密钥策略属性基加解密方案,其存在的缺点是密文长度随着属性增加而线性增加,在通信过程中消耗用户大量的通信带宽。进而提出了属性加密的改进方案,基于密钥策略属性加密,提出具有固定密文长度的可验证外包解密方案,并对其安全性进行了证明。

Abstract: The traditional key policy attribute based encryption and decryption scheme, The disadvantage is that the ciphertext length increases linearly with the increase of the attribute, Consume a large amount of communication bandwidth in the communication process. In this paper, an improved scheme of attribute encryption is proposed. Based on key policy attribute encryption, An Attribute-Based Encryption with Efficient Verifiable Outsourced Decryption and Fixed Ciphertext Length is proposed, and its security is proved.
Key words: Keywords: KP-ABE, outsourced decription, verifiability
