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.

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.

A mobile pay-TV service is one of the ongoing services of multimedia systems.Designing an efficient mechanism for authentication and key distribution is an important security requirement in mobile pay-TV systems. Until now, many security protocols have been proposed for mobile pay-TV systems. However, the existing protocols for mobile pay-TV systems are vulnerable to various security attacks.Recently, Wang and Qin proposed an authentication scheme for mobile pay-TV systems using bilinear pairing on elliptic curve cryptography. They claimed that their scheme could withstand various attacks. In this paper, we demonstrate that Wang and Qin's scheme is vulnerable to replay attacks and impersonation attacks. Furthermore, we propose a novel security protocol for mobile pay-TV systems using the elliptic curve cryptosystem to overcome the weaknesses of Wang and Qin's scheme. In order to improve the efficiency, the proposed scheme is designed in such a way that needs fewer scalar multiplication operations and does not use bilinear pairing, which is an expensive cryptographic operation. Detailed analyses, including verification using the Automated Validation of Internet Security Protocols and Applications tool and implementation on FPGA, demonstrate that the proposed scheme not only withstands active and passive attacks and provides user anonymity but also has a better performance than Wang and Qin's scheme.
