Application Of RSA Algorithm In Remote Sensing Image Data Transmission System

With the rapid development of network technology,more and more people transmit data through the network,and the amount of data is increasing.Because of the existence of virus and hackers,it is dangerous to transmit data through the network.In addition,a large number of data transmit through the network,which can easily cause network congestion,resulting in low efficiency of data transmission.Remote sensing image data is widely used in many fields,such as military,scientific research,economic construction and environmental protection in China,and its importance can not be underestimated.With the development of remote sensing,the transmission quantity of remote sensing image data on the network is becoming larger and larger.Therefore,it is of great significance to solve the security and efficiency problems of remote sensing image data in the process of network transmission.The content of the paper is part of the grid sharing supervision system in the two phase of the high resolution two resource satellite grid system.I studied the encryption algorithms and large data transmission deeply.The main work of this paper is as follows:(1)Participate in the analysis and design of the grid sharing supervisory subsystem.(2)Design and implement the module of remote sensing image data protection.Using the signature and verification signature function of RSA algorithm,complete the two-way identity authentication between the data receiver and the sender.Combining RSA algorithm with AES algorithm,AES algorithm is used to encrypt data,RSA algorithm is used to encrypt the keys of AES algorithm,giving full play to the advantages of the two algorithms,so as to improve data security.(3)Design and implement the module of remote sensing image data transmission.Using distributed,GridFTP and other technologies to realize the efficient transmission of data.
