摘要：Vehicular cloud facilitates a dynamic set of vehicle users to form a cloud and share the resources and services to make safe journey. A public encryption key which is shared among the users, so that anyone participating in the cloud can send a message securely and efficiently to the vehicular cloud. Users can join or leave the group efficiently without triggering a completely new key agreement protocol, which will greatly benefit the users in the vehicular cloud. We define a generic construction of dynamic asymmetric group key agreement by combining a traditional authenticated group key agreement, public key encryption and signature. We evaluate the performance of the scheme, in comparison with existing scheme.
