Drone Registration Phase Sample Clauses

Drone Registration Phase. { } 1) The drone Dj chooses its unique identity DIDj, and submits the registration request DIDj to the regis- tered CC through a secure channel. 2) Upon receiving the request, the CC checks whether the hash value H1(DIDj s) already exists in its identity- verifier database TDID. if it already exists, rejects the request. Instead, the CC generates a random number kj and computes PIDj = H2(DIDj s kj), sj = H3(DIDj PIDj s kj). Then, the CC deliver the tuple PIDj, sj into each drone. Besides, the CC stores the tuple H1(DIDj s), kj into its identity-verifier database TDID. 3) After receiving the tuple, the drone Dj keeps sj secretly to complete the registration process. Then, it declares the related information DIDj, PIDj , which are publicly available to all the legal vehicles.

Drone Registration Phase. By the execution of this phase, the drone registers with the control center (CC) to get a secret key. Figure 4 shows the interactions between the drone and the CC during this registration phase. The following is a detailed description.
