Of course, anyone attempting to use the information has to be technically capable and adventurous.Ī lot of the hardware which enables or supports unlawful access to IT systems (e.g.ĪTM card skimming the illegal copying of information from the magnetic strip of a credit or ATM card) appears to be coming from those regions. There are also dedicated forums online to help would-be criminals access satellite TV and Pay-TV without a subscription.
Many digital TV watchers use techniques such as card sharing or internet key sharing to spread the cost of a Pay-TV subscription among tens or hundreds of people. Modern cards are better, but the techniques for getting into them are also better.
If hackers can open up the card and get to the key, they can extract the key and use it to make cloned cards. Just like hiding it inside a (very thin) brick.ĭES is a symmetric-key algorithm, which means you use the same key to encrypt and decrypt. Of course, Pay-TV subscribers would have to remember the key, and have to enter it into their decoder - very inconvenient, but very safe.
If your lock (algorithm) is faulty, youll find out quickly enough and replace the lock. Thats a bit like hiding your door key inside a brick or under a flower pot once the secret (that the key is in the brick) is discovered, you have no security.Įverybody knows how your door security works (you put the right key in the lock and turn), but that only works if you have the key. Other information is also stored on the chip subscriber ID, subscription details, billing details, censorship filters and so on.Īn algorithm is a recipe for doing something in this case, for scrambling and descrambling the digital signal.
