Integrated OTP-based user authentication and access control scheme in home networks

In this paper, we propose a new user authentication (UA) scheme based on one-time password (OTP) protocol for home networks. The proposed scheme is to authenticate home users identification who uses home devices. Several techniques such as biometrics, password, certificate, and smart card can be used for user authentication in the same environments. However, such user authentication techniques must be examined before being employed in the environment where home devices have low efficiency and performance. Here, we present the important security functions of home networks. The proposed authentication protocol is designed to accept the existing home networks based on one-time pass-word protocol. Also, it is well suited solution and is quite satisfactory in terms of home networks security requirements, because of requiring low computation that performs simple operations using one-way hash functions. Our proposed scheme can protect illegal access for home services and devices and it does not allow unnecessary service access although they are legitimate users. Therefore, it allows the user to provide real-time privilege control and good implementation for secure home networks.
