Thank you very much. Can you tell me then, if I can tamper with the
semi-permanent keys or are they stored within the device also. I need to
know whether I can overwrite them in some way or I have to work without
augmenting the existing authentication and key exchange scheme at all.
Thanks in advance.

Dragomir
