摘　　要：现有的安全通信方法受限于60000 kB数据量,存在摘要对等数目不稳定的问题。为此,文章提出基于改进DES算法的网络链路安全通信方法。该方法通过网络链路安全协议建立连接,验证双方身份;利用最短路径优先协议,结合数据库信息,确保可信连接适应网络环境;基于密文位数,使用DES算法延长密钥,使之与明文位数匹配;设置访问权限,运用双线性映射配对特定属性,并通过加密算法处理,实现安全通信。实验证明,传输数据量稳定在90000 kB,提升了效率,解决了摘要对等数目不稳定的问题,提高了通信性能。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.
