Re: CAN + security != CAN and would break things
Encryping the canbus data leads to one thing - the vehicle is eventualy not repairable. A wonderful piece of planned obselesance.
I point the reader in the direction of Vauxhaul/opel following the PSA takeover.
How long before the relevant servers become unavailable and the canbus cant be read, decrypted or modified. Several modules on the Astra (for example) cant be serviced/replaced without access to the central server.
Indeed updates for the infotainment/satnav system have allready dried up.
No update is available that shows the new A14 around Huntingdon ( yes, yes read the f@$king roadsigns). What other module have or will develop a bug that needs an update (well the auto lights on function for a start!)
Cars made before about 2005 can be fixed with mechanical and electrical skills.
Todays cars would also need a crypro and software engineer.
