摘要：Authenticating a node in mobile ad-hoc networks is a challenging task due to theirdynamic and resource constraint infrastructure. For this purpose, MANETS adopt two kinds ofapproaches Public key cryptography and identity based cryptography. In Public Key Infrastructure(PKI), Certi cate Authority (CA) is responsible for key management. In order to adopt it toMANET, the job of the CA must be distributed. The master secret key is shared among thenodes of the MANET, to self-organize the network without a central authority.The key is sharedbased on Shamir secret sharing scheme with bi-variate polynomial to make the MANET fully self-managed by nodes.In this paper, we considered PKI based scenario and proposed a new scheme toauthenticate a node using BLS signature which is light weight compared to the existing schemesthus making it suitable for MANET.
