A Secure Data Dissemination in a DHT-Based Routing Paradigm for Wireless Ad Hoc Network

Figure 8

Illustration of the node authentication/verification and the joining process in 3D-SRP. (i) The newly joining node generates its credentials after receiving hello messages from the neighboring node(s) and sends its own public components and hash value of the identity card (IC) to the neighboring node(s). The neighbor node(s) gaze physically and use the RSS method to calculate the closeness to establish a trust. It decrypts the received information and ensures the data integrity to validate the IC; after IC validation, the neighboring node share its IC along with hash value. The newly joining node checks its validity. The verification and authentication process is a chain of trust and an issuance of the certificate after validating the ICs. (ii) The joining process of 3D-SRP is according to the joining process of 3D-RP as discussed earlier.
