Group key management in multicast networks plays a crucial role in data communication environment. Also, key management deals with distribution of keys among group members and maintaining the keys. The lack of security services, communication overhead, computation overhead, etc. Enables us to concentrate on creating new innovative ideas. A key distribution algorithm in the reviewed protocols does not provide much security in group communication networks. The contribution of this research is to investigate all the available key management schemes and to design the secure and efficient key management scheme in multicast network for achieving a secure communication between the group members. The proposed scheme, dynamic architecture and performance analysis of secure and efficient key management scheme, provides a secure variable UID-based key management scheme which protects non-group members from the access of data and generation of static group key which reduces computation cost at any change in the multicast network. The periodic renewal of group key using proactive secret sharing scheme provides greater security during communication. The proposed authentication process ensures data integrity and confidentiality during communication and the encryption mechanism used in dynamic architecture and performance analysis of secure and efficient key management scheme completely eliminates the communication, computation overhead, and network traffics. The analysis shows that the proposed key management scheme comprises of the most reliable methods for key generations and key distributions and provides better performance in terms of security requirements and other services.
