Group Join Operations Sample Clauses

Group Join Operations. In [7], ▇▇▇▇▇▇▇, et al. defined a family of auxiliary key operations required for dynamic group support – e.g., group member join and leave – and proposed a multi-party extension of ▇▇▇▇▇▇-▇▇▇▇▇▇▇ key exchange that supports these operations. The protocols presented in this paper can be readily extended to support group member join operations. Indeed, the mass join of j new group members to an existing t-client group can be achieved with fewer than j transmissions by suitably adapting Algorithm 1. However, member leave operations are not readily supported in our protocols. When a member leaves, the group key must be refreshed.
