An environmental monitoring data sharing scheme based on attribute encryption in cloud-fog computing.

Environmental monitoring plays a vital role in environmental protection, especially for the management and conservation of natural resources. However, environmental monitoring data is usually difficult to resist malicious attacks because it is transmitted in an open and insecure channel. In our pape...
