Certificateless ID-based authentication using threshold signature for P2P MANETs

As far as the security of MANET (mobile and ad hoc network) is concerned, it depends upon the secure authentication especially for P2P MANETs. Identity based encryption was introduced to construct Public Key without requiring a certificate. Therefore, certificateless authentication combined with threshold digital signature and efficient key generation using identities such as IP address, are the challenging issues in front of researchers. In this paper we have addressed the problem of identity based secure authentication employing well-known RSA algorithm and secret sharing to generate threshold signature on a message.
