A Distributed Multicast Encryption and Management Solutions Based on Security Agent
Ping Zhang, Liang Sheng Zhou · 2014
In order to avoid re-key of secure multicast and raise the efficiency of secure multicast, a new method of multicast encryption based on the RSA public key system is put forward. Based on the analysis of the manuscript, the new method has the function that using one key for encryption and many keys for decryption. The method does not need to update private key of everyone in the group when any member changes and satisfies the requirements of secure multicast of forward/backward confidentiality and collusion freedom. By analyzing communication mechanism of the security agent model, simulating performance of network node’s sending data packets and applying the multicast encryption method, a distributed security multicast management program based on security agent model is designed, which ensure that the users in the communication group can share the multicast information in the intranet safely.
