The existing secure communication methods are limited by 60000 kB of data and have the problem that the number of abstract peers is unstable.Therefore,this paper proposes a network link security communication method based on improved DES algorithm.The connection is established through the network link security protocol to verify the identities of both parties.Using the shortest path first protocol,combined with database information,to ensure that trusted connections adapt to the network environment.Based on the ciphertext bits,the DES algorithm is used to extend the key and make it match the plaintext bits.Set access rights,use bilinear mapping to pair specific attributes,and use encryption algorithms to process,to achieve secure communication.The experimental results show that the data volume is stable at 90000 kB,which improves the efficiency.Solve the problem of the unstable number of abstract peers and improve the communication performance.
