Key Management Scheme

A robust and efficient key management scheme is necessary for mobile ad hoc networks (MANETs) to ensure its security. CPK (Combined Public Key) is a recently developed public key algorithm, which has advantages comparing with other public key system, such as low storage overhead and calculation demand. Some key management approaches based on CPK have been proposed for MANETs in recent years. However, CPK is vulnerable to collusion attack which may bring about terrible threats. In this paper, a novel key management scheme based on double matrix CPK (DMCPK) is put forward, which is resistant to collusion attack. This key management scheme is described in details, including key generation and updating. Simulation experiments are implemented based on the simulation tool OPNET and show the effectiveness of the proposed scheme.

Key Management Scheme

This paper proposes a hierarchical key management scheme in the mobile Ad hoc networks. In this scheme, there are two kinds of server nodes: the special server nodes and the ordinary server nodes, such that only when two kinds of server nodes collaborate can they provide a certificate service. In order to satisfy this special application, we design a new secret sharing scheme for splitting the system private key, in which it generates two different kinds of shares of the system private key: the special share and the ordinary share, where it needs at least one special share and t ordinary shares to recover the system private key, thus we call it threshold scheme. Furthermore, we present a distributed signature scheme for a user’s certificate in the mobile Ad hoc networks based on this secret sharing.
