Modifications to the physical key wouldn’t help, as the signature and data wouldn’t match. The physical key would simply contain a digitally signed piece of data with any critical information: the meter that should receive it the owner’s ID, if any the amount of electricity purchased timestamp. The public key would be in the meters, probably with one of the cheap crypto-chips protecting & using it. The private key would be held by the utility company to sign a particular credit. I think I wasn’t clear about how my scheme would be used, so I’ll give some specifics for you to review. The issue here is unique in “non-technical losses” in that normal decent good customers that didn’t really think they were doing anything wrong ended up in trouble. They are not a cure-all, but they do address other issues. Two-way communications (aka AMI) meters are more expensive and have communications infrastructure costs beyond “token meters”, and have their own issues/attack vectors. Such tokens are typically encrypted and valid only for a specific meter and date range, although exceptions exist and may be the exploit. Most meters of this type can also export entered tokens, which can be checked against the master system to make sure they match. Detecting the fraud is easy, and may include a signature (ID) of the original token generation if it is a clone of some valid master key. They see your meter shows a usage of X, you have only paid for Y, you owe the difference. At some point you take your key back to a vending point, which sends a total kWh reading upstream. No actual details of what happened, so I can only make some guesses: We typically use STS/IEC-62055-41 token based meters as well as AMI. I’m in the prepaid electricity industry, but not in Europe. The error probably gets picked up the second value add after the hacked card is used. I assume that the end user will not be able to add value to the cloned card (hundreds of people turning up with the same card ID is a little obvious), so they would need to officially add vale to their old card which would raise the issue “how they got the last $50” I assume the card has a record of the meter reading and corresponding last payment. (BTW Most modern payment cards can prevent this by encrypting RAM data differently from EEPROM data)

decremented the on chip EEPROM) but some simple changes to the code can make this communication happen with the RAM rather than the EEPROM. Ideally the meter should not add the value until it verifies that the card has subtracted the value (i.e. Since the meters cannot communicate with each other, they have no way of knowing that the cloned card is being used in multiple locations. It could also be a cloned card, but that is a little harder, because you now need to get the cloned chips manufactured. The easiest hack of this kind is to simply prevent the on chip EEPROM being written, so they buy an official card, destroy the EEPROM write circuit, and use it on lots of meters. It is true that the stored data could be encrypted with a two key crypto system but this does not necessarily prevent the hack because it appears they are selling / using a card based upon an official original card. even if it is simply for mutual authentication.

Septem2:47 have not read all the details of the hack BUT for offline payment cards it is very difficult to get around the need for a single shared secret. Tags: cons, fraud, keys, scams, utilities They then trap people and ratchet up the sales price to customers terrified they will have to pay twice something Scottish Power confirmed is starting to happen here in Scotland. Clever.Ĭonmen sell people the energy credit and then warn them that if they go back to official shops they will end up being charged for the energy they used illegally. But by then, the criminals are long gone. The system detects the fraud, in that it shows up on audit at a later time. If they use this, it can be detected the next time they top up their key legitimately.

The conmen have cracked the system and can go into people’s houses and put credit on their machine using a hacked key. Normally people visit a shop to put credit on their key, which they then take home and slot into their meter. The pre-paid power meters use a key system. Criminals across the UK have hacked the new keycard system used to top up pre-payment energy meters and are going door-to-door, dressed as power company workers, selling illegal credit at knock-down prices.
