An Extensible Authentication Protocol with Transport Layer Security and One Time Password in the Multi Hop Mesh Network

The multi hop mesh networkan extension of wireless mesh network by ad hoc networkis one promising wireless network architecture in the near future. Securing access network is the first protection against attacker access to network services. Authentication is an essential for securing the access to the network. TLS/SSL (Transport Layer Security/Secure Socket Layer) protocol is one famous secure protocol for secure communication and authentication. However, implementation mutual authentication with client certificate is very complicated and high cost for wireless network. This paper proposed a combination of TLS/SSL and One Time Password (OTP) for mutual authentication and secure communication protocol. TLS/SSL protocol is used to authenticate server and make secure TLS/SSL tunnel between client and server. After that OTP is used to authenticate user over the secure TLS/SSL tunnel. OTP is a good way to protect system from dictionary or brute force attack. The combined model SSL and OTP is a strong authentication and secure communication protocol and it can be applied in the real world.
