Hi,
I am new to this forum. So please pardon any mistake. I have a simple idea about enhancing security of data transmitted between two ZigBee modules. This, of course would be implemented at micro-controller level using Embedded C. The idea is as follows:
When the data packet is sent for the first time, the auto update code is sent after the stop code of the first data packet.
The previous auto update code defines the location of the next auto update code that is now sent along with the next data packet. In this way the location of auto update code is not fixed and would randomly change, hence the security of the next data packet is strong and that data packet cannot be easily obtained by some third party.
Auto update code defines two functions. The location of the next auto update code and also what will be the next start and stop code, which will change randomly each time data is transmitted between transmitter and receiver.
I wanted to ask whether this idea is feasible. If yes, has such work been implemented before? I am new to ZigBee and would appreciate any help and advice.
Regards,
