ABSTRACT:
A method and system are provided for delivering event messages in a secure scalable manner. A network includes an event distribution device serving as an event generation device for generating and disseminating an event message through the network to event distribution devices serving as edge event delivery devices having recipient devices connected thereto. Event messages may be encrypted at the event generation device for each of the destination recipient devices or event messages may be encrypted at each of the edge event delivery devices for delivery to respective recipient devices connected thereto. A signing key may also be included with the encrypted message such that the respective recipient devices may authenticate a sender of the encrypted message based on the signing key. Encryption keys may be established based on policies of the network of event distribution devices or based on policies of the respective recipient devices.
