Sensing node of IoT (Internet of Things) is commonly designed with It's CC2530 as a core chip at present. In order to ensure the security of sensitive data transmitted between the nodes, and access permission control for the sensing node, a pair of encryption nodes-encryption sensing node and access control node are designed based on AES (Advanced(More)
Aiming at the lack of uniform mathematical model for multivariate graphs representation based on coordinate, a general model based on complex matrix is presented by analyzing and studying the traditional multivariate graphs such as radar chart, scatter plot, trigonometric polynomial graph, parallel coordinate, constellation graph. This model provides a(More)
