Based on Social Network Theory Security Identity Authentication Protocol Research on MANET

In the backdrop of the social network theory, Mobile Ad Hoc Network(MANET) security risks, and technical problems faced by is particularly important. Wireless self-organizing network with the traditional network in there are many different places, but they all have the same purpose of solving the problem of information security and identity authentication etc. This paper mainly studies the MANET security authentication protocol, because each other between the sensor and the gateway node provide relevant certification is always a difficult problem to the field, and the security is not guaranteed under offline password guessing attacks, in order to overcome these gaps, this paper puts forward the improvement scheme, and the solutions are compared with those of the traditional scheme of Das, summed up the improvement plan to improve the effectiveness and safety of the original agreement.
