Basic Assumption The [RFC 4919] describes two security concerns as follows; In Section 4.6 Security: IEEE 802.15.4 mandates link-layer security based on AES, but it omits any details about topics like bootstrapping, key management, and security at higher layers. Of course, a complete security solution for LoWPAN devices must consider application needs very carefully. In Section 5 Goals: Security Considerations: Security threats at different layers must be clearly understood and documented. Bootstrapping of devices into a secure network could also be considered given the location, limited display, high density, and ad-hoc deployment of devices. ? This draft will feed out the above requirements In addition, existing IP security technologies will be simplified to be implemented on the 6lowpan small devices. 6lowpan security architecture will shed off lots of fat from IP security technologies whenever available. IEEE 802.15.4 AES (Advanced Encryption Standard) will be used for 6lowpan security architecture in conjunction with IP security whenever available. |
