An efficient heterogeneous key management approach for secure multicast communications in ad hoc networks

In a mobile wireless ad hoc network, mobile nodes cooperate to form a network without using any infrastructure such as access points or base stations. Instead, the mobile nodes forward packets for each other, allowing communication among nodes outside wireless transmission range. As the use of wireless networks increases, security in this domain becomes a very real concern. One fundamental aspect of providing confidentiality and authentication is key distribution. While public-key encryption has provided these properties historically, ad hoc networks are resource constrained and benefit from symmetric key encryption.In this paper, we propose a new key management mechanism to support secure group multicast communications in ad hoc networks. The scheme proposes a dynamic construction of hierarchical clusters based on a novel density function adapted to frequent topology changes. The presented mechanism ensures a fast and efficient key management with respect to the sequential 1 to n multicast service.

“…In general, a session is defined as either public or private. Both types are defined by the level of session access control required to receive or transmit data within the multicast group [6]. Public sessions are typically encountered on the Internet Multicast Backbone (MBONE) and are supported by the dynamic nature of multicast communications (i.e., knowledge of the multicast address is often the only requirement for membership).…”

“…In order to improve overall system efficiency, the Distributed Registration and Key Distribution (DiRK) protocol distributes linear initial keying and rekey functions among active group members [6]. However, a question of peer trust may arise because the registration and key distribution functions are distributed in such a broad fashion.…”

INTRODUCTIONMulticast communication as defined in [1] is an efficient means of distributing data to a group of participants. In contrast to unicast communications, multicast routing permits a single IP datagram to be routed to multiple hosts with minimal redundant transmission within a network. Membership in a multicast group is often highly dynamic, with receivers entering and leaving the multicast session without the permission or explicit knowledge of other hosts. The inherent cost and resource benefits of multicast routing and data delivery are clear; however, the group-oriented communication paradigm presents new and unique technical challenges beyond traditional network security approaches.Potential security threats to multicast communications are similar to those encountered in unicast transmissions. Threats include the unauthorized creation, alteration, destruction, and illegitimate use of data [5]. In the case of multicast traffic, because of the inherent broad scope of a multicast session, the potential for attacks may be greater than for unicast traffic. It is desirable to secure these vulnerabilities while maintaining some of the efficiency and performance benefits of multicast service.The field of multicast networking and related security issues is a broad technical subject. Within the space limitations allowed, we discuss some relevant technical issues and performance tradeoffs to consider when applying security and key management techniques in support of multicast networking. First, we provide a brief background of multicast technology and potential network security threats and issues. Second, we explore the application of existing and proposed security techniques for multicast networking, including key distribution, dynamic key management, and reliability issues. Throughout this paper we hope to summarize performance and security policy considerations within the context and impact of overall architectural performance.

“…Broadly, the existing key management schemes are categorized as Centralized group key management protocols, which involve a central entity that has the responsibility of distributing the group key to the group members [20,21,5,14,12] . Decentralized group key management protocols, where a group is divided into subgroups, where each group has its own manager [13,6,15] and Distributed group key management protocols, where there is no involvement of any entity, which distributes the group key to the group members [18,2,3]. Each group member participates in the group key generation or it may be done by a single group member.…”

Designing a key management scheme for secure group communication is a challenging task. There are several tree based and non-tree based group key management schemes. In the existing non-tree based group key management schemes, the rekeying and storage costs are mostly in linear with the number of members in the group. Also, in some of the efficient tree-based group key management schemes, the rekeying and storage cost is a function of the number of group users. We propose a rekey efficient centralized group key management scheme in which communication, storage and computation costs are constant. In the proposed scheme, each user has to store only two keys. We compare the proposed scheme with some of the existing tree and non-tree based group key management schemes and show that the proposed scheme is rekey and storage efficient.
