A New Key Management Scheme For Large-Scale MANET
Pan Dong, Zhu Pei-dong · 2006
In this paper, we propose a key management system, which uses proxy CA mechanism to provide comprehensive public key authentication service. In our scheme, every CA group consists of some server nodes that use threshold signature to manage key certificates. A higher level CA group can distribute proxy signature key shares to a lower level CA group through the new algorithm we designing. Our scheme has good scalability, lower overhead, and better security, so it is suitable for the large-scale MANET
