Abstract
Disclosed are a robust and reliable edge storage method for the Internet of Things and a system therefor. A data owner server splits and encrypts raw data into an encrypted data segment, sets a trusted data access control policy and sends it to a third-party proxy server, and sends the encrypted data segment and the trusted data access control policy to a processing server; the processing server stores the encrypted data segment based on a totally local reconstruction code scheme, and forwards the request sent by a data requester server to the third-party proxy server; the third-party proxy server determines whether the data requester server that sends the request is trustable according to the trusted data access control policy, if it is trusted, then sends decrypted information to the data requester server through the processing server; the data requester server decrypts the encrypted data segment according to the decrypted information to obtain the raw data.
