smart meters

On the radio this morning someone said that theirs had a SIM card in
and it reported their reading back to base every night. That is
probably the safest option and removes the need for a van to comb the
streets reading each unit.

I'm sure people will try getting that card out and making free calls
from it though. I'm also thinking bad thoughts about sniffing, MITM,
fake SMS/GPRS connections. Lucky I haven't got time to do the project
I've already got on let alone new ones!

Subject: [Pauldotcom] smart meters

Hi
Some utility providers are looking at rolling out smart meters for gas
and electricity which they can read remotely. Does anyone know how
that works? What are they using to connect to the device to send out
the data? If it is over your broadband then it won't be long till
someone sniffs the packets and sends fake readings back, if it is
wireless and they have a guy drive past then there are similar
sniffing problems, you also have to worry about interference. They
could have a GSM card in, in which case, how long till someone cracks
one open and tries to use the card in a phone, I imagine it would be
locked to a single number but people would try.

I can't think of a secure and problem free way to do this. Any ideas?

Here is a BBC video about the meters.
