we are developing security product. We will have a wireless transceiver which will act as a coordinator and sensors has to be connected to the coordinator. The sensors should be enrolled to the coordinator inorder to join the network. No other device should join the network without the knowledge of the coordinator.It should not join the network automatically.How to implement this in Bitcloud?
From avr@atmel.com they replied we can use permission table. But they said
"Permission Table implementation is not included by default in BitCloud
public releases."
In our product we want to implement permission table.
What we have to do.
How can we implement permission table in our product. |

| The only real way to do this is to use security and set network key only on the devices that need to have it. |

In our product we want to enroll the other devices to the coordinator so that it can allow devices to join the network.
In the Bitcloud Developers guide, in page number 70 (section 8.6), they have given a topic permission table. this is what we exactly needed.
How to implement this in our product.
Is it possible or not.
If yes how to implement it.
If No, why it is so, even it is part of the bitcloud stack.
Security related things also we will implement, but permission table is the thing exactly what we want to implement. |

| No, it is impossible since this functionality is disabled in public releases. It is disabled to keep stack footprint at a reasonable value; this function is targeted to a more powerful platforms. |

I didnt get what exactly you are coming to say.
we are ready to pay to use that option as that much security is required in our product.
what do you mean by powerful platforms. |

No amount of money will make stack fit into ZigBit with Permission Table enabled. If you want to try you should contact avr@atmel.com and ask them.

ARM for example. Not that it is enabled there by default.
But you need to understand that PT works only against devices that decided to play by the rules.
If attacker will want to join it will send frames using allowed device MAC address.
The only real way to secure your network is to use preconfigured network key that is never transfered over the air. |

| SAM7X_EK, SAM3S_EK, for example. But keep in mind that PT is disabled in public released there as well, since it is pretty pointless feature anyway. |
