The Research Of Safe Transport Mechanism Of Wireless Network Based On Immunology

With the rapid development of communication technology and network technology, people are using network more widely and get dependent on it increasingly. The emergence and development of wireless network can meet people's need of using network at all times and places, but it is confronted with more security problems than wire network. In view of such situation, the paper emphasizes the study of the transport mechanism of wireless network security on the basis of ordinary security problems. My main research works and achievements mentioned in the thesis are following:First, based on the analysis of present wireless network security problems, the paper exponds the design of a wireless network transmission system in the light of immune system of the living organisms, and built a wireless network security transmission model on the basis of immunization.Secondly, based on the in-depth analysis of wireless network routing AODV protocol, the paper introduces the design of a dual-digital signature mechanism to improve and optimize the protocol against the existed security risks, at the same time, the signature algorithm is designed and implemented. The paper also presents a simulation to verify the effectiveness and feasibility of improved routing protocol for wireless network. It turned out that the improvement and optimization achieved a good result.Finally, based on the analysis of the structure of wireless network advanced Encryption Standard AES, the paper describes an encryption algorithm used in the process of the wireless network secure transmission, and also made a logical design for the encrypted circuit of the wireless network secure transmission.
