Supporting differentiated secure communications among heterogeneous electronic devices
First Claim
1. A gateway apparatus supporting differentiated secure communications among heterogeneous electronic devices, the gateway apparatus comprising:
- a first communication port configured to communicate via an associated first communication network of a first network type with a first associated device having a first secure communication capability, the first communication port further being configured to communicate via an associated second communication network of a second network type different than the first network type with a second associated device having a second secure communication capability different than the first secure communication capability; and
gateway logic operatively coupled with the first communication port;
wherein the gateway logic selectively authenticates the first associated device for group membership into a first Secure Communication Group (SCG);
wherein the gateway logic selectively authenticates the second associated device for group membership into the first SCG;
wherein the gateway logic selectively communicates Secure Communication Group Keys (SCGKs) to the first associated device having the first secure communication capability and to the second associated device having the second secure communication capability for generating session keys by the first and second associated devices for mutual secure communication in accordance with the group membership of the first and second associated devices in the first SCG.

Abstract
A gateway apparatus supports differentiated secure communications among heterogeneous electronic devices. A communication port communicates via communication networks of different types with two or more associated devices having diverse secure communication capabilities. The gateway logic selectively authenticates the associated devices for group membership into a Secure Communication Group (SCG), and selectively communicates Secure Communication Group Keys (SCGKs) to the devices having the diverse secure communication capabilities for selectively generating session keys locally by the associated devices for mutual secure communication in accordance with the group membership of the associated devices in the SCG.

8. A method of supporting differentiated secure communications among heterogeneous electronic devices, the method comprising:
-
communicating by a communication port of a gateway apparatus via an associated first communication network of a first network type with a first associated device having a first secure communication capability; communicating by the communication port of the gateway apparatus via an associated second communication network of a second network type different than the first network type with a second associated device having a second secure communication capability different than the first secure communication capability; selectively authenticating by the gateway logic the first associated device for group membership into a first Secure Communication Group (SCG); selectively authenticating by the gateway logic the second associated device for group membership into the first SCG; selectively communicating by the gateway logic Secure Communication Group Keys (SCGKs) to the first associated device having the first secure communication capability and to the second associated device having the second secure communication capability for locally generating by the first and second associated devices session keys for mutual secure communication in accordance with the group membership of the first and second associated devices in the first SCG. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. Logic encoded in one or more tangible non-transient computer readable media for execution by an associated processor and when executed by the associated processor the logic being operable to:
-
communicate by a communication port of a gateway apparatus via an associated first communication network of a first network type with a first associated device having a first secure communication capability; communicate by the communication port of the gateway apparatus via an associated second communication network of a second network type different than the first network type with a second associated device having a second secure communication capability different than the first secure communication capability; selectively authenticate by the gateway logic the first associated device for group membership into a first Secure Communication Group (SCG); selectively authenticate by the gateway logic the second associated device for group membership into the first SCG; selectively communicate by the gateway logic Secure Communication Group Keys (SCGKs) to the first associated device having the first secure communication capability and to the second associated device having the second secure communication capability for locally generating by the first and second associated devices session keys for mutual secure communication in accordance with the group membership of the first and second associated devices in the first SCG. - View Dependent Claims (16, 17, 18, 19, 20, 21)
