CRAW: Combination of Re-Keying and Authentication in Wireless Networks for Secure Multicast Increasing Efficiency of Member Join/Leave and Movement

TL;DR

This paper introduces CRAW, a new secure multicast approach for wireless networks that combines authentication and group key management to improve efficiency and security during member join, leave, and movement.

Contribution

CRAW uniquely integrates member authentication with group key management, reducing re-keying overhead and enhancing security in wireless multicast scenarios.

Findings

Re-keying overhead reduced from O(log2 n+1) to O(1) during joins.

CRAW maintains security while improving efficiency.

Stores main list for managing mobile members' locations.

Abstract

Recently, the number of requests for multicast services through the wireless networks has been increased. However, for successful deployment, security and efficiency of content delivery must be provided at first. This paper presents a new approach for secure multicast in wireless networks. This approach, CRAW (Combination of Re-keying and Authentication in Wireless networks) combines member authentication procedure with group key management protocol to provide an efficient group re-keying process. One-time password is proposed for member authentication and CKC (Code for Key Calculation) is suggested for group key management in wireless networks. In fact, the combination of authentication with group key management in wireless networks results in a simple and secure mechanism both for authentication and group key management while mobile members join/leave a group or move inter-area. Simulation results show that CRAW reduces re-keying overhead at join from O(log2 n+1) to O(1) while security requirements are saved. Also, CRAW introduces storing a main list to manage mobile members' location while they move intra-group inter-area.
