This document proposes a new authentication scheme for mobile pay-TV systems. Traditional schemes are inefficient and costly because they require one authentication message per request. The proposed scheme provides one-to-many authentication, broadcasting one message for multiple requests, improving efficiency. It also enables handoff authentication for security during handoffs and uses identity-based encryption for anonymous user authentication protecting privacy. The new scheme has better performance and communication costs than traditional schemes and is well-suited for mobile pay-TV systems.

A Secure and Efficient Authentication Scheme for Access Control in
Mobile Pay-TV Systems
Abstract
In a mobile pay-TV system, a large number of messages are exchanged for
mutual authentication purposes. In traditional authentication schemes, with one-to-
one delivery, one authentication message per request is delivered from a head end
system to subscribers. This results in the delivery of a large quantity of messages
and therefore is inefficient and costly. Moreover, since most traditional schemes
use an RSA-based signature for identity validation and nonrepudiation of
communication, they suffer from high communication costs. Due to its wireless
nature, mobile pay-TV is vulnerable to attacks during hand-off. As traditional
schemes do not support hand-off authentication, they are insecure during hand-off.
With these shortcomings, they are not suitable for mobile pay-TV. In this paper,
we propose an innovative authentication scheme, in which, by providing one-to-
many facility, only one authentication message for multiple requests is broadcasted
from the head end system to subscribers. By employing bilinear property of pairing
and elliptic curve cryptography, our scheme provides one-to-many facility in the
case of multiple requests for the same service in a short period of time. This new
scheme achieves better broadcast efficiency and performance on communication
costs than traditional ones. Additionally, this scheme provides a hand-off
authentication mechanism to protect the access of services while preventing attacks
during hand-off; therefore, the scheme is more secure to support access control.
Moreover, to provide anonymous authentication for protecting identity privacy, the
scheme adopts an identity-based scheme while traditional schemes do not apply.
The scheme inherits advantages of the identity-based scheme that a public key
does not need to be certificated, the certification authority mechanism will not be
needed and the key exchange overhead can be reduced. With these advantages of
our scheme, it is well suited for mobile pay-TV system.
