Abstract
Official abstract text for this publication.
A new approach for a transport protocol for sensor data collection, such as a smart grid is described. In one embodiment of the invention, each server avoids keeping security and communication state per client through the notion of a secure “state-token”. The state token is issued with each server message and is subsequently attached to corresponding client messages delivered to the server. An implementation is provided in which the server encrypts and authenticates the associated session state, and then gives the resulting encryption for the client to temporarily store and return to the server with a next message. In this way, a server does not keep session state after sending the encryption back to a client and can quickly restore session state when the next message from the client arrives.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of secure communication for executing a session between a client and a server in a communications network, said method comprising the steps of: sending a session connection request from said client to said server; receiving from said server an acknowledgement message, said acknowledgement message including a state token representing a state of association between said client and said server, said state token being encrypted and authenticated by sa…
