Abstract

A system comprises an interface and a processor. The interface is configured to provide a request to join a publish group from a client or a point to point communication link of a lattice mesh; and receive a group key or a host public key. The processor is configured to determine whether a message has been received; in response to the message having been received, determine whether the message is to be sent on; in response to the message being determined not to be sent on, decode the message using the group key or the host public key; determine whether to store the message in a backfill database; in response to determining to store the message in the backfill database, store the message in the backfill database.

First claim

What is claimed is:

1. A system, comprising:
an interface configured to:
provide a request to join a publish group from a client or a point to point communication link of a lattice mesh; and
receive a group key, wherein the group key includes a shared secret and a public key of an ephemeral keypair; and

a processor configured to:
determine whether a message is available to send; and
in response to a determination a message is available to send:
encode the message using the group key; and
send the message.

2. The system of claim 1 , wherein the group key is received from an asset database.

3. The system of claim 1 , wherein the processor is further configured to:
in response to a determination a message is not available to send, wait until a message is available to send.

4. The system of claim 1 , wherein the group key is a symmetric key.

5. The system of claim 1 , wherein the group key is used to encrypt/decrypt messages.

6. A method, comprising:
providing a request to join a publish group from a client or a point to point communication link of a lattice mesh;
receiving a group key, wherein the group key includes a shared secret and a public key of an ephemeral keypair;
determining, using a processor, whether a message is available to send; and
in response to a determination a message is available to send:
encoding, using the processor, the message using the group key; and
sending the message.

7. The method of claim 6 , wherein the group key is received from an asset database.

8. The method of claim 6 , further comprising:
in response to a determination a message is not available to send, waiting until a message is available to send.

9. The method of claim 6 , wherein the group key is a symmetric key.

10. The method of claim 6 , wherein the group key is used to encrypt/decrypt messages.

11. A computer program product, the computer program product being embodied in a tangible non-transitory computer readable storage medium and comprising computer instructions for:
providing a request to join a publish group from a client or a point to point communication link of a lattice mesh;
receiving a group key, wherein the group key includes a shared secret and a public key of an ephemeral keypair;
determining whether a message is available to send; and
in response to a determination a message is available to send:
encoding the message using the group key; and
sending the message.

12. The computer program product of claim 11 , wherein the group key is received from an asset database.

13. The computer program product of claim 11 , further comprising:
in response to a determination a message is not available to send, waiting until a message is available to send.

14. The computer program product of claim 11 , wherein the group key is a symmetric key.

15. The computer program product of claim 11 , wherein the group key is used to encrypt/decrypt messages.
