A scheme for reducing the overhead of member changes in secure multicasting environments is proposed. The scheme requires transmission of only the identifications of participants to be revoked. For environments where storage overhead is an issue, serial revocation is recommended. However, when the issue is bandwidth rather than storage, then parallel revocation will prevail. Either way, the revocation process is blindly carried by all participants collaboratively, including the target. The communication overhead is less than that of the leading surveyed scheme. The scheme can be implemented using either hardware or software. |
