摘要
复用信息的传输信道受到攻击时,整体传输效率降低,对此,设计一种基于云计算的数据中台局域多路复用信息可信传输方法。在云环境下建立数据中台局域多路复用数据的传输模型,确立通信双方路径选择原则;利用云计算进行数据传输对称加密,详细设计密钥的选择、加密和解密过程,优化数据传输过程中的多路资源分配;根据节点数据分配不同信道下的数据量,优化传输效率。算例分析结果表明,在多次测试下,设计的可信传输方法未出现传输失败情况,且上传、下载速率均优于传统方法,验证了设计方法的有效性。
When the transmission channel of multiplexed information is attacked,the overall transmission efficiency will be reduced.Therefore,a trusted transmission method of data middle platform local multiplexed information based on cloud computing is designed.In the cloud environment,the transmission model of local multiplex data in the data middle platform is established,and the path selection principle of both communication parties is set.Then,the symmetric encryption of data transmission is carried out by using cloud computing,and the key selection,encryption and decryption process is designed in detail,which optimize the multi-channel resource allocation in the data transmission process,and the data volume under different channels is allocated according to the node data to optimize the transmission efficiency.The example analysis results show that under multiple tests,the designed trusted transmission method has no transmission failure,and the upload and download rates are better than the traditional methods,which verifies the effectiveness of the design method.
