Research question

in view of the network encryption network

the transfer of the process

when encryption appear delay

delay process

the network node vulnerable to outside attack

cause safety hazard.This paper presents a Feistel algorithm based on improved the data encryption technology

through the key technology to combine traditional divided into four levels

greatly saving algorithm calculated time

solve the problem of time delay.Experimental results show that the new algorithm in computing time

reduced sharply

increased the safety and good results have been achieved.
