Operator Services

4. Scenario: Integration WPAN to Operator’s Network
<Sept 2010>
Scenario: Integration WPAN to Operator’s Network
Home Network
UMTS
Operator Core
Network
Operator Services
or Internet Services
Home sensor sends the information via 3G fixed terminal and service platform to mobile users, or vise versa
Without authentication and authorization, malicious nodes can
Inject false data into the network, misleading decision makers;
FFD
RFD

5. Requirements Authentication Manageability
<Sept 2010>
Requirements
Authentication
Operator can authenticate both the cellular device and the peer devices within the PAN (directedly or indirectedly)
Manageability
Keep track of the status of peer devices, either to schedule attendance or to track the behavior

6. Gap Analysis What’s been done What’s not been done Manageability
<Sept 2010>
What’s been done
What’s not been done
Authentication
Can authenticate the cellular devices
Confidentiality
Keys available to encrypt the data between cellular devices and the mobile core network
Envelope available to encapsulate encrypted data between peer devices
Authentication
Authenticate the peer devices
Account the peer devices
Confidentiality
No key management
No secure association protocols
No group key association
Manageability
No manageability functionality

7. Possible Directions of WPAN Authentication
<Sept 2010>
Possible Directions of WPAN Authentication
Open system
Admits any devices through the coordinator to access the operator network
Shared key authentication
Admits devices to demonstrate their knowledge of a shared secret
Extensible authentication
Asymmetric authentication using Public key cryptography
More extensible ways based on 802.1X and EAP

8. Authentication & Secure Association
