基于身份的并行增量移动云存储方案

针对移动云计算环境中的数据存储问题,提出了一种基于身份的并行增量移动云存储方案.该方案引用了并行计算思想,使用密文聚合技术,充分挖掘了现有移动客户端的性能,在效率和能耗之间达到了平衡;使用增量代理重加密算法,在将部分计算迁移至云计算中心的同时,提高其整体性能;不使用传统公钥证书,既减少了密钥管理压力,也实现了信息的保密性和完整性.实验表明,该方案提高了CPU的使用率,具有较强的可用性.

Parallel Incremental Mobile Cloud Data Storage Scheme on Identity-Based Cryptography

Aiming at data storage issue in mobile cloud computing environment, a parallel incremental mobile cloud storage scheme based on identity-based proxy re-encryption has been proposed. Parallel computing is brought into the scheme, which aggregates ciphertexts, and the existing mobile client performance is full excavated for the balance between efficiency and energy consumption. Incremental proxy re-encryption is used to migrate the part computing to the cloud computing center, improving the overall performance at the same time. Certificates in traditional public key cryptosystem are not need anymore, which not only reduce the pressure of key management, and also ensure the confidentiality and integrity of the information. Experimental results show that the scheme improves the utilization of CPU and has considerable availability.
