Node Authentication Using BLS Signature in Distributed PKI Based MANETS
Authenticating a node in mobile ad-hoc networks is a challenging task due to
their dynamic and resource constraint infrastructure. For this purpose, MANETS
adopt two kinds of approaches Public key cryptography and identity-based
cryptography. In Public Key Infrastructure (PKI), Certificate Authority (CA) is
responsible for key management. In order to adapt it to MANET, the job of the
CA must be distributed. The master secret key is shared among the nodes of the
MANET, to self-organize the network without a central authority.The key is
shared based on Shamir secret sharing scheme with bivariate polynomial to make
the MANET fully self-managed by nodes.In this paper, we considered PKI based
scenario and proposed a new scheme to authenticate a node using BLS signature
which is light weight compared to the existing schemes thus making it suitable
for MANET
