Secure push and status communication between client and server

Abstract

Systems and methods of authentication and authorization between a client, a server, and a gateway to facilitate communicating a message between a client and a server through a gateway. The client has a trusted relationship with each of the gateway and the server. A method includes registering the client with the gateway. The client also constructs the address space identifying the gateway and the client. The client communicates the address space to the server. The client receives an identity identifying the server. If the client authorizes to receive a message from the server through the gateway, the client informs the authorization to the gateway. The client puts the identity identifying the server on a list of servers which are authorized to send messages to the client. In addition, the client communicates the list of servers to the gateway.

What is claimed is: 
     
         1 . A system for authenticating and authorizing a client and a server through a gateway to facilitate message communication, the system comprising:
 a processing unit; and   a memory encoding instructions that, when executed by the processing unit, cause the processing unit to:
 request, by the server, a token from the client; 
 receive, by the server, the token from the client, the token identifying the client and the gateway and authorizing the server to push messages to the client through the gateway as long as the token has not been revoked; and 
 send, by the server, a message along with the token to the gateway, the gateway forwarding the message to the client after the token is validated by the gateway.
