The latest in stupid security tricks comes from the folks at Toyota with their Prius RFID key fobs. They apparently employ 64-bit encryption on these fobs, making it quite possible to simply brute force break the encryption. And it's not like they need the key, either. All they've gotta do is make your key emit data through the air and they can crack the encryption.
The complaint from Toyota? It costs too much. Well guess what, folks, good security isn't cheap. Customers who are paying out their posterior for a Prius deserve a better system. 64 bit encryption can be cracked in an hour. How about 256 bit encryption, which shouldn't be crackable within our lifetime?

2^64 is not vulnerable to a bruteforce, the algorithm is broken your ignorances is upsetting you fail to understand that a larger keysize would slow things down and require more expensive and unneccessary processing power, the combination of encryption and key requires two sets of skills to bypass the security increasing the security of the system exponentially versus wouldbe thieves regaurdless of the cryptography
