Abstract
Official abstract text for this publication.
To address the security requirements for cyber-physical systems, embodiments of the present invention include a resilient end-to-end message protection framework, termed Resilient End-to End Message Protection or REMP, exploiting the notion of the long-term key that is given on per node basis. This long term key is assigned during the node authentication phase and is subsequently used to derive encryption keys from a random number per-message sent. Compared with conventional schemes, REMP improves privacy, message authentication, and key exposure, and without compromising scalability and end-to-end security. The tradeoff is a slight increase in computation time for message decryption and message authentication.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of secure communication between a group of publishers and a group of subscribers in a network, said method comprising the steps of: assigning by one, or more authentication servers a long-term key on per node basis to said publishers in the group of publishers and subscribers in the group of subscribers during a node authentication phase; and using said long term key to derive encryption keys from a random number per-message set, wherein a publish…
