Abstract :
Recently, Sun and Leu proposed an efficient authentication scheme for access control in mobile pay-TV systems based on pairing and elliptic curve cryptography. In Sun and Leu´s scheme, there exist two fatal security flaws, including 1) failure in subscriber authentication and 2) vulnerable to unauthorized access, which contradict to the security claims of Sun and Leu´s scheme. To meet the claimed security requirements, we strengthen Sun and Leu´s scheme with only lightweight modifications.
