摘要：This paper is intended to solve the problem of high capacity of streaming media and data access privilege management in a broadcasting environment. For this, an access privilege sharing management technique that enables a safe streaming media service is designed by using AONT-based XOR threshold Secret Sharing on the basis of cloud computing. Specifically, encryption in protocol is composed of the first encryption that maintains the confidentiality of data by performing the AES encryption of streaming media data, and the second encryption that makes an access privilege management function carried out and satisfies variability and redundancy by the distribution storage of AES key. The proposed scheme assures security against a collusion attack between the malicious users and cloud servers due to the decryption privilege sharing because the first encryption and the second encryption output (header, body) is stored and shared through other channels (Privilege Manager Group, Media Service Provider) respectively.
