“…These methods suffer the heavy computation burden. In [6], a subscriber first has to register his subscriber information with a signature to a provider by applying public key cryptosystem. When a subscriber wants to subscribe to any programs, he uses his device to send a subscription message to the provider.…”

One of the promising multimedia services is the mobile pay-TV service. Due to its wireless nature, mobile pay-TV is vulnerable to attacks especially during hand-off. In 2011, an efficient anonymous authentication protocol for mobile pay-TV is proposed. The authors claim that their scheme provides an anonymous authentication to users by preventing intruders from obtaining users' IDs during the mutual authentication between mobile subscribers and head end systems. However, after analysis, it was found that the scheme does not provide anonymous authentication and users can be easily tracked while using their anonymous identity. The scheme is also subject to denial of service attack. In this paper the deficiencies of the original scheme are demonstrated, and then a proposed improved scheme that eliminates these deficiencies is presented.

“…The provider then sends a receipt with a signature for confirming this subscription to the subscriber. However, the scheme [6] only protects the customers' privacy, but not the provider's [2]. In [7], an "e-ticket" scheme for the authentication of pay-TV system is proposed.…”

“…With the number of digital TV subscribers increasing rapidly, the efficiency of authentication and key establishment become a key factor that affects the performance, but traditional CAS did not consider the efficiency of authentication in interactive mode [3] . In addition, the subscriber management system (SMS) manages a large number of identity's information, so the privacy protection has become a basic demand [4] , especially in the use of many triple play services such as home networking, home security, family health, etc. This will inevitably reflect their own information.…”

Now many television operators are providing subscribers with more and more value-added service. When people use these services they will have the risk of leaking personal information, such as the watching habit, the privacy problem has become a hot topic to the public. This paper proposes a scheme of CAS anonymous authentication in two-way network, and the scheme uses group signatures based on the elliptic curve. It meets both efficient authentication and transaction tracking needs, and can also protect user's privacy in a certain extent.

Summary Pay‐television has become a popular added‐value service in mobile systems. Recently, Yeh and Tsaur proposed an authentication scheme for mobile pay‐television based on Sun and Leu's scheme. However, we found that Yeh and Tsaur's scheme has some security flaws, ie, impersonation attack with knowing mobile set's identity card, the adversary impersonates the head‐end system attack, the replay attack, the denial‐of‐service attack, and collusion attack. To overcome these problems, in this paper, we propose an improved scheme by storing a head‐end system signature and using a password. In addition, our proposed scheme keeps all the merits of Yeh and Tsaur's scheme. Furthermore, the performance analysis shows that the computation cost and the communication cost of our scheme are decreased dramatically compared to Yeh and Tsaur's scheme.
