Efficient and scalable multicast key management using attribute based encryption
Hongyong Jia, Yue Chen, Xiuqing Mao, Ruiyu Dou · 2010
Although the multicast group key management scheme using the flat table with attribute-based encryption can resist colluding attacks, the final scheme is inefficient regarding the communication and computation cost in the rekeying phase. In this article, we propose an efficient and scalable hierarchical multicast key management by exploiting the attribute relations in the flat table scheme with attribute-based encryption.
