Many new cars contain technologies that make them vulnerable to theft by hacking. The Mercedes S550 boasts a keyless antitheft ignition system which uses a 40-bit code to unlock doors and start the car. Keyless entry systems use radio frequency identification (RFID) to unlock cars from several feet away. The system produces a new 40-bit code every time it is used. Other cars shut down if someone drives them without the necessary RFID keychain. Researchers at John Hopkins University managed to unlock and start a 2005 Ford Escape SUV without the key by using a laptop with attached RFID reader to intercept only two challenge- response pairs. Such thefts have been demonstrated in the wild as well: Radko Soucek of the Czech Republic is believed to have stolen several cars this way. The John Hopkins researchers recommend abandoning 40-bit encryption for the stronger 128-bit Advanced Encryption Standard (AES). http://news.com.com/Gone+in+60+seconds--th..._3-6069287.html Anyone know the type of encryption system Toyota uses on the Prius? Hopefully it is 128-bit encryption system.
<div class='quotetop'>QUOTE(woodprius @ May 10 2006, 01:40 PM) [snapback]252894[/snapback]</div> Nope, late Toyota models still use the 40-bit TI-RFID system. I wrote to Toyota about this. You should too. We should make our voices heard.
If someone wants your car, they are going to get it regardless of what kind of key you use. The odds of your car getting stolen by someone hacking your SKS are slim to none.
Agreed. It is cheaper, faster, and easier to just drag it on to a flatbed truck. If someone is that committed to driving the car away, I'd rather they crack my SKS code remotely than hold a gun to my head and demand the keys.
Here's the thread I was referring to: http://priuschat.com/forums/gen-ii-prius-main-forum/82275-dangerous-smart-key.html
Relay attacks resulting in many Toyota vehicles stolen in the Ottawa area. Seems like it is a bit too easy. https://www.cbc.ca/news/canada/ottawa/toyota-lexus-relay-attack-1.5380947
and this, ladies and gentlemen is why you need a good dog. not some little moron fuzzy yapper mutt with a stupid sounding name either (though those will likely wake you up if a dirt bag comes near your house), but a real dog that will bite the crap out of anyone you tell it to. and ideally a shotgun. but seriously, I don't think these 3rd world scum are gonna steal 10-15 year old prii anyway.
I’d offer advice on a great location in your Prius to store your handgun when it is not carried on you according to local laws but that his of 1st amendment writing about the 2nd amendment rights...don’t go over well on forums. Do what you need to to to be safe and secure in your Prius.
There is a forum here for that: Fred's House of Politics. This thread is not about you being safe and secure while in a Prius, but about keeping the Prius secure when you are not in it.
Good information. Thank you very much. I have since reread about the Toyota encryption as it compares to Mercedes Benz. It seems that cost in manufacturing and setup is more and then passed on to the buyer reflected in the price of the car. Justifiable so it would seem.
