IMPLEMENTING RSA ALGORITHM FOR FULLY DISTRIBUTED CERTIFICATE AUTHORITY IN MANET

Mobile wireless ad hoc networks that are resistant to impersonating nodes are necessary for distributed systems used in security applications. Many secure protocols in mobile ad hoc networks depend on the public key infrastructure. Nodes in MANETs are still vulnerable to different kinds of attacks so multiple certificate authorities (CAs) distributed over the network, each with a periodically updated share of the private key, are usually adopted as a solution. Establishing a distributed virtual CA is an important tool to ensure the security of the mobile ad hoc networks. This article proposes a new scheme for RSA key-sharing scheme based on threshold secret sharing algorithm. In this scheme, the sub secrets are covered when the MANET makes the reconstruction of the polynomial function.
