METHOD AND APPARATUS FOR PROVIDING SECURE COMMUNICATION AMONG CONSTRAINED DEVICES

摘要

In one example, an apparatus such as an authorization server and method for secure communication between constrained devices issues cryptographic communication rights among a plurality of constrained devices. Each of the plurality of constrained devices comprises no more than one cryptographic algorithm code module per cryptographic function. The method includes receiving a cryptographic communication rights request associated with at least a first of the plurality of constrained devices in response to a cryptographic algorithm update request, and includes providing a response including an identification of a subset of the plurality of constrained devices that have cryptographic communication rights with the identified first of the plurality of constrained devices. A software update server then updates the cryptographic code modules in the sub-set of the plurality of constrained devices.

1. A method for secure communication between constrained devices comprising:
issuing, by an authorization server, cryptographic communication rights among a plurality of constrained devices where each of the plurality of constrained devices comprises no more than one cryptographic algorithm code module per cryptographic function; receiving, by the authorization server, a cryptographic communication rights request associated with at least a first of the plurality of constrained devices in response to a cryptographic algorithm update request; and providing, by the authorization server, a response comprising an identification of a subset of the plurality of constrained devices that have cryptographic communication rights with the identified first of the plurality of constrained devices.
