Abstract


With advances in sensor manufacturing process development and wireless communication technology , wireless sensor networks have been widely used in military , commercial and civilian areas . Wireless sensor network is constructed by way of self-organization by the hundreds of thousands of wireless sensor nodes mobile peer-to-peer network . Unlike the traditional ad hoc networks , wireless sensor networks by computing power transmission capacity and storage capacity , and many other restrictions , energy efficiency has become a very important design goals . Data fusion technology can effectively reduce the amount of data transmission , the prevention of collisions , has been widely used in practical applications . Data fusion to reduce energy overhead while it also brings a lot of security risks , vulnerable to a variety of potential attacks , such as : data eavesdropping , data tampering , falsification of data , data replay attacks . Therefore , the establishment of the safety data fusion program has an important significance for the protection of the security of the data fusion results . This study is mainly for lossy data fusion application layer from the two aspects of the confidentiality and integrity of the program design appropriate security mechanisms : First , this paper presents a hidden data fusion transmission scheme . The program uses the data multiplexing thought , to be able to guarantee that an attacker can not steal data fusion results by eavesdropping or captured nodes , with better security . Compared with the existing corresponding program has the following advantages : the same threshold of network security , the program has a smaller transmission overhead , better performance and flexibility and prevent conflict . Secondly , the paper presents a hierarchical multi-hop network data fusion data integrity authentication scheme , the program of the corresponding program to expand its data from a single path filtering and intrusion detection protocol extensions into a stratification within the network data fusion integrity authentication scheme . The program supports the integrity to identify intermediate nodes and base station data fusion results , to ensure that the attacker can not inject illegal data to the network by capturing nodes or forged node , while reducing illicit data on the consumption of network resources , but also in the security and flexibility , better performance .
