| 摘 要： | 在云计算环境下，绝大多数信息处理和存储都被转移到云中心，用户终端的计算和存储能力将逐渐弱化。本文针对这一趋势，提出一种适用于云计算的多接收方代理重加密方案，充分利用云中心的分布式计算能力，使用随机数重用和密文聚合技术，大大降低了计算和传输负担，实验表明本方案具有较高的效率。

| Abstract: | In cloud computing, data processing and storage are placed in the cloud center, and the terminals of users not required to be powerful. A distributed parallel proxy re-encryp- tion scheme is proposed, so as to get with to distributed environment. The distributed par- allel proxy re-encryption algorithm obtains the higher utilization rate of several computer nodes. The messages are optimized parallel with randomness reusing and cipher text aggre- gation, which greatly reduces the computation and transmission overheads. Experiment result shows that the scheme is very efficient. |
