Abstract:

In recent years, with the rapid development of Internet industry, mobile terminal has become an indispensable part of people's life. However, due to the lack of infrastructure and other external factors, mobile cellular Internet cannot provide high-quality data communication services in specific environment. As the next generation Internet technology, self-organizing network can form a temporary multi-hop self-governing system with a group of mobile nodes with wireless transceiver devices, which provides users with emergency communication services in limited area in specific environment. Aiming at the problems of lacking security mechanism for wireless self-organizing network data and short coverage, this paper proposes the self-organizing network node authentication and confidential communication system, which can authenticate the legitimacy of nodes and apply data encryption scheme to ensure effectively the security of network node data during the transmission. It has been verified that in the OLSR self-organizing network environment, relatively stable transmission efficiency can be obtained, and to a certain extent, the security of network nodes data can be effectively guaranteed.
