چکیده
This paper proposes two frameworks for secure multicast on active networks. The frameworks exploit the computational power of active networks to provide the security desired for multicast, while removing drawbacks in traditional approaches. The main security component in the frameworks is the Active Capability(AC) which replaces the passive session key. The main advantages of using an AC are lack of an asymmetric key pair requirement for authentication, lack of session key modification requirement when a member leaves the group and a highly distributed and scalable key distribution mechanism independent of availability of a group owner.

Multicast Routing in Wireless Sensor Networks: A Distributed Reinforcement Learning Approach
Wireless Sensor Networks (WSNs) are consist of independent distributed sensors with storing, processing, sensing and communication capabilities to monitor physical or environmental conditions. There are number of challenges in WSNs because of limitation of battery power, communications, computation and storage space. In the recent years, computational intelligence approaches such as evolutionar...
متن کاملFlexible Secure Multicasting in Active Networks
In this paper we describe an alternative, exible approach to multicast security in active networks. Traditional schemes for securing multicast communication have key management and scalability problems for many typical applications. In addition, traditional mechanisms are not capable of expressing exible, situational security policies for multicast sessions and participants. Our scheme exploits...

Many emerging applications in mobile ad hoc networks involve group-oriented communication. Multicast is an efficient way of supporting group oriented applications, mainly in mobile environment with limited bandwidth and limited power. For using such applications in an adversarial environment as military, it is necessary to provide secure multicast communication. Key management is the fundamenta...
متن کاملSecure Multicast over Multihop Wireless Ad Hoc Networks
In this paper we address the problem of secure multicast of data streams over a multihop wireless ad hoc network. We propose a key management protocol that aims at solving problems that are specific to ad hoc networks such as mobility, unreliable links, and multihop communication cost. The main idea is to have group members actively participate to the multicast group security therefore reducing...
متن کاملSecure Group Key Management Scheme for Multicast Networks
This paper proposes a scheme to provide security to dynamic multicast VoIP systems efficiently. Security is usually provided by encrypting the media packets sent from a user to other users with the help of a shared key called the session encryption key. The most time consuming process in a dynamic multicast VoIP environment is the group key management. Whenever there is a change in the group me...
