Abstract

This invention is a system and method for verifying a sender of messages on a mobile network. Software on a cloud messaging service generates a public/private key pair. The private key is securely retained in a cloud wallet service and is accessible to a messaging cloud service (the trusted sender). The public key is shared with a subscriber device that receives messages from the messaging cloud service. The cloud messaging service receives an inbound message for the subscriber device from a trusted enterprise application via a secure connection. The cloud messaging service signs a special header to the message with its private key. When the message is received by the subscriber device, the public key resident on the device verifies the message header signed with the public key of the cloud messaging service thereby verifying the sender.
