An ID-based node key management scheme based on PTPM in MANETs

In order to resolve the problems of node multiple keys management and protected storage in mobile ad hoc networks, a new identity-based node key management scheme combined with next generation protected storage of portable trusted platform module was presented for mobile ad hoc networks. In the scheme, the combined public key based on elliptic-curve cryptography was adopted to generate multiple keys, which were protected and managed by the next generation protected storage of portable trusted platform module. We show that our scheme is semantically secure under the elliptic-curve DDH assumption. Also, performance evaluation of proposed scheme in a real-world ad hoc network indicates the feasibility in practice. Copyright © 2015John Wiley & Sons, Ltd.
