利用RLWE构造基于身份的全同态加密体制
Identity-Based FuIIy Homomorphic Encryption from Ring Learning with Errors ProbIem
摘要
Abstract
Fully homomorphic encryption provides a new idea on the solution of many problems,such as the whole life cycle of data privacy protection on cloud computing.Currently,the existing fully homomorphic encryption schemes share a common flaw of large size public keys.We construct an identity-based fully homomorphic encryption which compromises the merits of both kinds of encryption from ring learning with errors to work in arbitrary cyclotomic rings.To make user’s i-dentity as the unique public key,our scheme has advantage in computational efficiency and key management.The security of our scheme strictly reduces to hardness of decision ring learning with problem solving in the random oracle model.关键词
