A novel authentication and key agreement scheme for peer-to-peer streaming

Reasonable and efficient security mechanism is the key to operating peer-to-peer (P2P) streaming systems. To save the cost of both communication and computation, ECC-based self-certified public key cryptosystems (ECCSCPKC) is introduced to construct the system security infrastructure. And its related security schemes are used for designing an efficient authentication and key agreement (AKA) protocol, which can protect against attacks from the outsider so that only registered user can access services with data confidentiality, integrity and authenticity.
