B-GKAP Leave Sample Clauses

B-GKAP Leave. In leave operation of B-GKAP, for the leaving participant Ui, par- ticipant Ui—1 executes generateAndSendPublicKey(·). Later on, participants Ui—1 and Ui—2 perform queryPublicKey(·). Moreover, participants Ui—1 and Ui—2 execute generateAnd- SendSecretKey(·). Eventually, all participants execute querySecretKeys(·). Based on Table 5.5, for B-GKAP1, total network transmission is N + 5 and commu- nication complexity of leave operation is Ct = O(N) where N is the remaining participant count in the group. For B-GKAP2, generateAndSendPublicKeyv2(·) and querySecretKeysv2(·) are exe- cuted for each organization. For the organization count M, total number of network opera- tions is M(N + 1)+ 4, and communication complexity is Ct = O(N).
