摘要:

全同态加密在云计算的数据和隐私安全领域有重要应用,但现有全同态加密体制普遍存在密钥、密文尺寸偏大的弊端,严重制约其实用性。为此,以环上容错学习问题为基础,提出环上重编码体制与基于属性加密体制,并与全同态加密体制结合,构造基于属性的全同态加密体制,该体制无需公钥证书,可实现对加密数据细粒度访问控制,与已有同类成果相比,大大缩短了密钥与密文尺寸。

Abstract:

The fully homomorphic encryption has important applications in the area of data security and privacy security of cloud computing,but the size of secret keys and ciphertext in most of current homomorphic encryption schemes were too large,which restricted its practical.To improve these drawbacks,a recoding scheme and a attribute-based encryption scheme based on learning with errors problem over rings were provided,then a attribute-based fully homomorphic encryption was constructed.The new scheme overcame the above mentioned drawbacks,because it did't need public key certificate,meanwhile,it can achieve the fine-grained access control to the ciphertext.Compared with similar results,proposed method decreases the size of keys and ciphertext greatly.

Key words: RLWE problem, recode, attribute-based encryption, fully homomorphic encryption
