类型可修改的基于身份代理重加密方案
A Dynamic Type and Identity-Based Proxy Re-Encryption Scheme
摘要
Abstract
Cloud storage is drawing tremendous attention in IT field. In it, an open challenge is to keep the privacy of users’ outsourced data and securely share users’ data. To address this challenge, proxy re-encryption (PRE) scheme is one of promising method. A dynamic type and identity-based PRE scheme will be proposed. This scheme not only obtains the traditional functions of PRE, but also allows a user to update the original types of his outsourced ciphertexts. Compared with the previous PRE scheme, the new feature makes the proposed PRE scheme more useful in practical applications.关键词
