Abstract

Techniques are disclosed for software development on utility devices. In an example, a utility device, responsive to validating a manufacturer signature, transitions to an isolated development mode. When in the isolated development mode, the utility device is restricted from joining a network and receives an application from a development computing system. The utility device validates a network signature and transitions to a network testing mode. When in the network testing mode, the utility device joins the network, registers with a head end system via the network, and executes the application. After a threshold amount of time has lapsed the utility device transitions to the isolated development mode.

Claims20

Dependent claims

A utility device comprising:

one or more processors and configured to operate in one or more of:
an endpoint mode, an isolated development mode, and a network testing mode, wherein:
when in the endpoint mode, the utility device is configured to:
communicate with other devices on a network;
access a manufacturer signature and a network signature;
validate the manufacturer signature against a reference manufacturer signature;
and
responsive to validating the manufacturer signature, transition to the isolated development mode;
when in the isolated development mode, the utility device is restricted from joining the network and is configured to:
receive, via a development port, an application from a development computing system;
execute the application on the one or more processors;
validate the network signature against a reference network signature;
and
responsive to validating the network signature, transition to the network testing mode;
and
wherein when in the network testing mode, the utility device is configured to:
join the network;
register with a head end system via the network;
execute the application on the one or more processors, wherein the utility device communicates with one or more other utility devices based on the application;
and
after a threshold amount of time has lapsed, transition to the isolated development mode.

18 more elements

A method comprising:

transmitting a request for a development certificate, wherein the request comprises a unique identifier of a utility device;
receiving a manufacturer signature and a network signature;
validating the manufacturer signature against a reference manufacturer signature;
and
responsive to validating the manufacturer signature, transitioning to an isolated development mode;
wherein when in the isolated development mode:
restricting the utility device from joining a network;
receiving an application from a development computing system;
executing the application;
validating the network signature against a reference network signature;
and
responsive to validating the network signature, transitioning to a network testing mode;
and
wherein when in the network testing mode:
joining the network and communicating with one or more utility devices connected to the network;
registering with a head end system via the network;
executing the application, wherein the application can communicate with the one or more utility devices;
and
after a threshold amount of time has lapsed, transitioning to the isolated development mode.

16 more elements

A system comprising:

a development computing system that is configured to:
transmit, to a validation server, a request for a development certificate, wherein the request comprises a unique identifier of a utility device;
receive, from the validation server, the development certificate, wherein the development certificate comprises a network signature and a manufacturer signature;
and
transmit the development certificate and an application to the utility device;
wherein the utility device comprises:
one or more processors;
a memory configured to store a reference manufacturer signature and a reference network signature, wherein the utility device is configured to communicate with the development computing system and operate in one or more of:
an endpoint mode, an isolated development mode, or a network testing mode, wherein:
when in the endpoint mode, the utility device is configured to:
communicate with other devices on a network;
receive, from the development computing system, the development certificate;
validate the manufacturer signature against the reference manufacturer signature;
and
responsive to validating the manufacturer signature, transition to the isolated development mode;
and
when in the isolated development mode, the utility device is restricted from joining the network and is configured to:
execute the application on the one or more processors;
validate the network signature against the reference network signature;
and
responsive to validating the network signature, transition to the network testing mode.
