Abstract
A method for securing group communications with reduced message overhead begins by initiating a secure group communication, where a group communication is secured based on security credentials of the group. The secured group communication is then provided to members of the group, where the secured group communication includes a secured message portion and an overhead portion based on the group, not each member. Each member of the group that receives the message determines that the secured message is group communication for its particular group. Each member then obtains at least a portion of the security credentials (e.g., the private decryption key) of the group to decrypt the secured group communication.
