英文摘要： When the information is transmitted with a high quality and security, how to keep the performance of network coding in a reasonable level？This problem has become a critical problem in wireless network communication that need to be solved urgently. Aiming at the prominent problems of network performance (such as throughput and energy overhead), security and fault tolerance exist in previous network coding research schemes, the objective of this program is to address the performance maintenance problem of intrusion tolerance based network coding by combining the information theory with compressed sensing theory, reduce the performance cost of secure network coding scheme that need to be sacrificed and expand the application area and capacity of network coding. The research contents include the fault tolerance and security of network coding and the compressed sensing based fault tolerance and security of network coding; the objective is to improve data transmission rate of network, solve the dropping, pollution and eavesdropping attacks problems, meanwhile, network system possesses low decoding complexity for recovering the original information. The research results will establish a solid foundation for secure, efficient and fault tolerant network coding, they also will provide important theoretical reference value
