Brief Announcement: A Synthetic Public Key Management Scheme for Large-Scale MANET

摘要

We introduce a new MANET structure model - party model - for the large scale MANET environment. For the party model MANET, we propose a new synthetic public key management scheme which applies web-of-trust and hierarchical trust simultaneously. The web-of-trust is used to design high efficient authentication between two nodes from the same party, and the frequent cooperation and communication inside a party can help to improve the security of authentication. In order to prevent falsification attack in remote authentication, we apply the hierarchical trust to establish CA in each party and use CA's certificate as the trust intermediary. In the whole, our scheme can get a good tradeoff among security, overhead and flexibility.
