Distributed Multicast Key Management Scheme Based on Elliptic Curve Cryptosystem
Tan Yun-meng · Journal of Chinese Computer Systems · 2006
Distributed secure multicasting is becoming very popular on the Internet. However, it presents several challenges, mainly in key bandwidth and overheads of key generation and rekeying. We propose a shared key mechanism based on ECC, and apply it to multicast to bring forward two distributed multicast schemes, which are high secure for secret keys of all members are embedded in. To compare with several previous works, the costs are smaller but rekeying efficiency higher at same secure strength.
