Abstract
The advance in information technology has made video service a market with great commercial value. As an example, in-vehicle infotainment has been introduced to vehicles with which customers can enjoy subscribed media services wherever they are. This paper investigates the authentication in commercial video services using a recently proposed protocol, the Sun-Leu protocol, as baseline. Several important security and performance requirements are revisited, including mutual authentication, anonymous authentication, one-to-many delivery, low communication cost and the security against replay attacks. We provide a detailed analysis of the Sun-Leu protocol against these requirements, based on which an enhanced authentication scheme is proposed. The new scheme is designed within the framework of the Sun-Leu protocol, preserves all merits of the original protocol and provides a higher level of security for video communication services.
