Ying Zhang, Shihai Lü, Pla Information · Journal of Zhengzhou Institute of Technology · 2005
This paper analyzes the architecture, number and update of keys in well-known protocols of GKMP and lolus. It finds out that the protocols have some vulnerability in security, such as single point lost and lack of updatability. A robust, updatable and extendable protocol for group key management is proposed.
