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. Onetime
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(log2n+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.
