Fully Self Organized of Certificate Authority in MANETs

摘要

A mobile ad hoc network (known as MANET) represents a wireless communication network, without a pre-existent subtraction or foundation and which is not reliant on any kind of centralized management. Various certificate authorities (CAs) distributed over the network, each with a periodically updated share of the secret key, is usually adopted. With this paper we hope to bring a strong contribution to making the public key management scheme more efficient especially for fully self-organized mobile ad hoc networks where the role of the dealer is played by all the nodes play. To ensure this means that each node must carry out by itself all the operations that imply nodes' public keys: initiation, distribution and revocation. The main objective of our approach is to enhance the process of building fully self certificate authority of nodes by using the Ham-line strong (n, t, n) VSS. Our proposal will provide the mobile ad hoc network flexible and efficient to make renewal and revoke certificate authority.
