SummarySince the early 1990s, engineers have proposed many mechanisms for providing confidential communications and data integrity in mobile ad hoc networks (MANET). The deficiency of fastened infrastructure makes mobile ad hoc networks more vulnerable to security threats than conventional wireless networks. MANET can be considered as a short-lived collection of mobile nodes that communicate with each other in between. All involved nodes in the network system share the responsibility for routing, accessing, and communicating. The main challenges on the design of MANET include high power saving and low bandwidth. The public key infrastructure (PKI) is a wellknown mechanism used to provide data integrity and confidential communications in MANET recently. The computation loads of PKI, however, are heavy to each mobile node in the cluster. Without adopting PKI cryptosystems to en/decrypt messages, we propose a novel version based on a variant Diffie-Hellman protocol. The novel method can preserve the forward and backward secrecy of group communications. Specifically, the new method outperforms related works in the computation overheads of involved nodes while communicating with other nodes.

In emergency tasks, cross-agency operations being carried out in disaster-hit areas require some supporting communication system for command and control. Mobile Ad hoc Network (MANET) is a very suitable way to meet such communication requirements since it can function without any pre-installed communication infrastructure. Owing to potential threats in the field environment and the unique features of MANET (e.g. the open nature of wireless links and the absence of security infrastructure), security of communications over MANET is a serious issue that is typically addressed by asymmetric cryptographic mechanisms. In this paper, we tackle issues critical to asymmetric key management in MANET, which almost invariably serves as a basis of security services in a network environment. To address the deficiencies of existing key management schemes, we propose the concept of mission-specific certificate to manage public keys in our scenario. For issuance and/or revocation of mission-specific certificate, a Mission-specific Certificate Authority (MCA), which consists of a collection of server nodes to operate the threshold cryptographic scheme, is proposed. Furthermore, to cater for the occurrence of network partitioning, which is common in highly dynamic MANET, we propose a partition-tolerant mechanism for MCA by introducing the notion of auxiliary server nodes. We discuss the security and performance of our scheme and show that our approach is a secure and partition-tolerant mechanism can effectively improve availability of the MCA.
