Optimizing deletion cost for secure multicast key management
Multicast and broadcast are efficient ways to deliver messages to a group of recipients in a network. Due to the growing security concerns in various applications, messages are often encrypted with a secret group key. The key tree model which has been widely adopted maintains a set of keys in a tree structure so that in case of groupmember change, the group key can be updated in a secure and ef...
متن کاملKey management for high bandwidth secure multicast
This paper brings up a new concern regarding efficient re-keying of large groups with dynamic membership: minimizing the overall time it takes for the key server and the group members to process the re-keying message. Specifically, we concentrate on re-keying algorithms based on the Logical Key Hierarchy (LKH), and minimize the longest sequence of encryptions and decryptions that need to be don...
متن کاملPerformance Optimizations for Group Key Management Schemes for Secure Multicast
Scalable group rekeying is one of the biggest challenges that need to be addressed to support secure communications for large and dynamic groups. In recent years, many group key management approaches based on the use of logical key trees have been proposed to address this issue. Using logical key trees reduces the complexity of group rekeying operation from O(N) to O(logN), where N is the group...
متن کاملAn efficient key management scheme for secure wireless multicast
In the future, many multicast services will take place in the wireless domain. However, before these services can successfully be deployed, security infrastructures must be developed that manage the keys needed to provide access control to content. In this paper, we present a method for designing multicast key management trees that are suitable for mobile wireless environments. By matching the ...
متن کاملKey Management for Secure Multicast over IPv6 Wireless Networks
Multicasting is an efficient method for transmission and routing of packets to multiple destinations using fewer network resources. Along with widespread deployment of wireless networks, secure multicast over wireless networks is an important and challenging goal. In this paper, we extend the scope of a recent new key distribution scheme to a security framework that offers a novel solution for ...
