Bluetooth initialization?

I am not very familiar with Bluetooth and its initialization processes. But what happens after I replace my car battery? So all electronics have been unpowered and are powered up again? Does Bluetooth also needs a re-initialization in that situation? If so, this could be in not such a secure environment, making it vulnerable for hackers?

I am a betting man so will put $100 towards claim that @jzolnier works for TI...I don't mind press releases, I ocasionally read them in my business...but I am not happy to see press releases sneaked in as "my own words"...I don't come to EE Times for that...Kris

@krisi: Did you write this sentence @jzolnier? Do you work for TI?

Well... if I were a betting man... (LOL)

TI has been working with our customers for years to help them ensure their wireless applications, including those using Bluetooth Smart, are safe from security attacks.

This is my opinion and technical belief. Again not to trivialize the challenge of security, it will always be at the top of the list of priorities for any of the use cases I mentioned, but I feel strongly that done properly BLE is very secure.

Are you expressing your own opinion @jzolnier? This reads like a press release

Excellent point. If someone breaks into my car & gains access to the CAN buses, maybe he can do some something. But any wireless link should remain completely isolated from those CAN buses, so that even if wireless security is somehow compromised, the worst that can happen is the doors are unlocked, the infotainment system is turned on or the driver's seat is moved.

users can be assured that additional layers of security will be used to ensure these vulnerabilities are not maliciously exploited

If wireless is not used where it is not needed, then one need not worry at all about wireless vulnerabilities.

We are witnessing a revolution in the auto industry, and wireless connectivity is at the center of that revolution. As vehicles have become more and more dependent upon electronics, security and reliability concerns have always been raised, ranging from fear of EM pulses being used to disable ECUs to hackers gaining access to the vehicle through a standard Bluetooth connection. Even today many keyless entry systems remain vulnerable to various types of attacks.

 

Bluetooth Smart technology inside the automobile will offer significant improvements to the user experience in many areas, and will also help manufacturers to produce more efficient vehicles.  Outside of the automobile, Bluetooth Smart technology is or will be used in medical applications, mobile payment systems, garage door openers, and residential and commercial locks. Each of these applications has security and reliability as paramount concerns.

 

TI has been working with our customers for years to help them ensure their wireless applications, including those using Bluetooth Smart, are safe from security attacks.  Regardless of any demonstrated vulnerabilities, users can be assured that additional layers of security will be used to ensure these vulnerabilities are not maliciously exploited, resulting in implementations that are highly secure.

Why Wireless

I can see very little reason to link functions like adjusting seats, mirrors and such by the use of a smart phone.  For some drivers replacing the Remote Keyless Entry fob with a smart phone makes good sense.  But for most functions why not use CAN bus or some other simple serial wired bus to do most of these functions.  Wireless in neat and cool but replacing a wired serial bus with a wireless bus seems like added complexity with little advantage.
