英文摘要 | Internet-of-Things (IoT) based applications are rapidly gaining popularity. Smart home is one of them; home security and safety, home automation, energy management and health surveillance are some applications of smart homes. Smart homes have enormous potential as well as enormous threat to security and privacy of the end users. Pay TV is considered as the likely entry points for IoT services into smart homes. Pay TV has evolved security techniques very similar to of IoT based smart homes services. Pay TV is an application of broadcast encryption schemes in which premium content is broadcasted only to subscribed users. The broadcaster needs assurance that only subscribed user can access premium content, so the program is encrypted with a group key shared among all subscribers. Thus, to share the key, Pay-TV systems require efficient and secure group key agreement (GKA). This research proposes an efficient and secure, dynamic, ID-based authenticated, asymmetric group key agreement (AAGKA) protocol for Pay-TV networks. Security is proved under the assumptions of the discrete logarithm problem (DLP) and decisional Diffie-Hellman problem (DDHP). Finally, comparison of the protocol with state-of-art protocols shows that the proposed protocol is highly efficient. |
