“…Many techniques have been proposed for receiver access control-little attention, however, has been paid to the sender counterpart of the problem. Examples of receiver access control include scalable multicast key distribution (SMKD) [12], group access control architecture for secure multicast and anycast (Gothic) [13], CRBR [11], and receiver access control in PIM-SM [14]. Examples of solutions that provide access control for receivers and senders are authorization stamp [15], IGMP extension for authentication of receivers and senders (IGMP RAC & SAC) [16], and keyed hierarchical multicast routing protocol (KHIP) [17].…”

SUMMARYMulticast communications concern the transfer of data among multiple users. Multicast communications can be provided at the network layer-an example is IP multicast-or at the application layer, also called overlay multicast. An important issue in multicast communications is to control how different userssenders, receivers, and delivery nodes-access the transmitted data as well as the network resources. Many researchers have proposed solutions addressing access control in IP multicast. However, little attention has been paid to overlay multicast. In this paper, we investigate the access control issues in overlay multicast and present OMAC: a new solution to address these issues. OMAC provides access control for senders, receivers, and delivery nodes in overlay multicast. The proposed architecture, which is based on symmetric key cryptosystem, centralizes the authentication process in one server whereas it distributes the authorization process among the delivery nodes. Moreover, delivery nodes are utilized as a buffer zone between end systems and the authentication server, making it less exposed to malicious end systems. To evaluate our work, we have used simulation to compare the performance of OMAC against previous solutions. Results of the simulation show that OMAC outperforms previous multicast access control schemes.

“…The main objective of a secure group communication protocol is to ensure the data confidentiality against outsiders such that only legitimate group members can recover the group data. Existing solutions for wired networks [19][20][21] are not well suited for WMNs as they fail to take into consideration the multi-hop communication paradigm featured by WMNs, as well as the communication security among mesh clients within the coverage of a mesh router. These protocols also do not exploit unique features of WMNs, such as the broadcast nature of wireless communication.…”

Wireless sensor networks (WSNs) and wireless mesh networks (WMNs) are popular research subjects. The interconnection of both network types enables next-generation applications and creates new optimization opportunities. Currently, plenty of protocols are available on the security of either wireless sensor networks or wireless mesh networks, an investigation in peer work underpins the fact that neither of these protocols is adapt to the interconnection of these network types. The internal cause relies on the fact that they differ in terms of complexity, scalability and network abstraction level. Therefore, in this article, we propose a unified security framework with three key management protocols, MPKM, MGKM, and TKM which are able to provide basic functionalities on the simplest devices and advanced functionalities on high performance nodes. We perform a detailed performance evaluation on our protocols against some important metrics such as scalability, key connectivity and compromise resilience, and we also compare our solution to the current keying protocols for WSNs and WMNs.

Video delivery network has been widely used across the Internet nowadays. The success of Video Portals is an evidence of this use. Due to its potential to turn into large infrastructures, there is a concern about its vulnerabilities. The communication among its elements must be secure enough to guarantee the availability, the secrecy and integrity of messages and the authenticity of its elements. We present in this work a secure communication protocol to meet such requisites in an efficient-since it meets the performance requisites for delivering the content to the users-and generic way-because it can be used by other distribution systems. The validity of this work is done in order to show that this proposal can meet the requisites of a secure video delivery system.
