A group key agreement scheme based on servers was developed to improve the poor scalability and efficiency of most existing group key agreement schemes based on clients which require each group member to participate in group key agreement on secure group communication system.In this scheme,key agreement was completed by only servers which directly connect to group member,which reduces the storage and communication costs of the group.One-way function which mapped from server keys to group keys is designed in client function library.Comparing with key agreement mechanism based on client,it makes a great progress in security and efficiency.
