Abstract�� In order to realize secure and efficient mobile node authentication in mobile ad hoc networks (MANET) which have no traditional public key infrastructure (PKI), a scheme consisting of identity-based cryptograph, distributed secrete sharing algorithm and elliptic curves encryption was proposed. Identity-based digital signature algorithm was briefly discussed. Lagrange interpolating polynomial was used to distribute master secret key among system nodes. A model describing secure node key issue was given, and a distributed procedure based on the given model was presented to securely issue node key by using elliptic curves encryption. The security and efficiency of the proposed algorithm was analyzed. According to the property of the bilinear pairing, the generation and update of session keys was discussed. The proposed authentication scheme could be used to realize efficient and secure authentication in distributed mobility scenarios, and to generate non-interactive one time session keys between two mobile nodes.
