摘　　要：当前云计算中心的去中心化数据共享过程用户属性混乱,易出现隐私数据泄露问题。提出新的云计算环境去中心化数据安全共享算法。结合短群签名和属性加密算法,定义修改用户和只读用户的属性条件,使符合条件的用户实现去中心化数据加解密。考虑云计算环境下丢包敏感、时延以及带宽敏感需求,根据待共享流的目的地址和源地址构建最短路径集,筛选路径构建数据共享安全度权重函数,利用采用比例选择算子选择转发路径,实现去中心化数据的安全共享。实验结果表明,与传统算法比较,所提算法的安全性更好、运行效率更高。实验结果验证了本研究为云计算环境数据的安全共享提供有力理论支撑。At present,the process of decentralized data sharing in cloud computing centers is chaotic in user attributes,and privacy data leakage is easy to occur.A new decentralized data security sharing algorithm for cloud computing environment is proposed.Combined with short group signature and attribute encryption algorithm,the attribute conditions of users and read-only users are defined to realize the decentralized data encryption and decryption for qualified users.Considering packet loss sensitivity,delay and bandwidth sensitivity requirements in the cloud computing environment,the shortest path set is constructed according to the destination address and source address of the stream to be scheduled,the security weight function of data sharing is constructed by selecting the path,and the forwarding path is selected by using the proportional selection operator to realize the security sharing of decentralized data.Experimental results show that the proposed algorithm is safer and more efficient than the traditional algorithm.The experimental results verify that this study provides strong theoretical support for the secure sharing of cloud computing environment data.
