一种适合云数据共享的身份代理重加密方案
Identity based proxy re-encryption scheme for secure cloud data sharing
摘要
Abstract
Currently most of the solutions of cloud data security storage required the data owner encrypted his data before out-sourcing the data to the cloud,but this method couldn't support flexible data sharing,especially for the multi-user setting. Aimed at solving this problem,this paper proposed a new identity based proxy re-encryption scheme,which didn't need the cloud to be completely trusted,but could also be used to share the data safely.In the concrete construction,this paper used a strongly non-forgeable signature scheme to let the encrypted ciphertexts be publicly verifiable,this scheme could also be cho-sen ciphertext secure in the standard model.For the proposed scheme can be used without certificate,support fine-grained ac-cess control and be very scalable,thus it can be used for secure data sharing in the cloud.关键词
