With the increasing complexity of cloud environments and the increasing demand for information sharing,a distributed collaborative information sharing platform based on a hybrid cloud architecture was designed.Design various functions of an information sharing platform in a mixed public and private cloud environment,and select appropriate storage locations for data by defining parameters such as sensitivity,spatial saturation,and access frequency of the shared platform data;the new data naming rules were adopted to name different data as primary or multi-level data,thus achieving efficient distribution of shared data;an improved public private key dual encryption technology was also designed to protect the data security of the sharing platform.By establishing three types of encrypted data:encryption key,permission matrix,and server ciphertext,and combining them with the cloud sharing platform again to generate re encrypted ciphertext,the designated data of the designated user can be securely shared.After experimental verification,the designed distributed collaborative information sharing platform has high performance in data storage,data transmission,and data security.
