Tesla is rolling out extra layer of security with ‘improved cryptography’
and optional ‘PIN to Drive’ feature
Tesla 推出"进阶加密"以及"PIN to Drive" 来增加额外的安全防护
Tesla has recently been gradually releasing new security features to make it
more difficult for thieves to steal their vehicles.
Today, Tesla started rolling out a new update with “improved cryptography”
for its key fobs and a new optional ‘PIN to Drive’ feature.
The new feature is optional and adds a new layer of security for owners who
don’t mind adding an extra step to be able to drive their Tesla.
今天，Tesla 推出一项新的更新，其中包括用于其钥匙卡的"进阶加密"，
和新的"PIN to Drive" 可选功能。
新功能是可选的，为那些不介意多一步骤才能启动Tesla 的车主添加了
一层新的安全防护。
According to the release notes, the new feature prompts a PIN to be entered
on the center screen before enabling the capacity to drive the vehicle.
In order to activate the feature, owners have to go in ‘Controls > Safety
and Security > PIN to Drive’.
根据说明，新功能会在启动车辆之前提示在中央萤幕上输入PIN。
为了开启该功能，车主必须进到Controls > Safety and Security > PIN to Drive。
以下不重要就不翻了...
Tesla also wrote in the release notes:
“We additionally added support for improved cryptography in our key fobs for
Model S to guard against other attacks.”
The updates and new feature come after a string of Tesla vehicle thefts
through relay attacks in Europe.
Tesla’s vehicles get rarely stolen thanks to its always-on advanced GPS
tracking feature. We recently learned that stolen Tesla vehicles in the US
have almost all been recovered: 112 out of 115.
But some more sophisticated thieves, especially in Europe, are still able to
get away with it due to those relay attacks with key fob.
It’s not a particular weakness of Tesla vehicles and any vehicle with a key
fob is subject to it, but Tesla is making it increasingly more difficult for
those attacks to work through those recent updates.
Recently, the company shared ‘tips’ to help prevent them, which include
disabling Passive Entry (Controls > Settings > Doors & Locks > Passive Entry
> OFF).
But if you want to keep the convenience of passive entry, you can also store
your key fob in some very simple signal blocking pouch when you are not using
it.
On top of it, owners will now have the option to use this new ‘PIN to Drive
’, which adds another layer of security.
心得/说明：
这项"PIN to Drive" 功能在现实生活中很常见，就是一个两阶段验证功能
例如有些网站在登录时除了要求你输入帐号密码，还会传送一组安全码到你手机要你输入
汽车的话，除了车钥匙，你自己再多加一道排档锁或方向盘锁也算是两阶段验证
这样可以避免车钥匙或钥匙卡被偷了小偷就能开走你的车
要输入密码才能开车的我就不晓得以前有没有人做过
麻烦知道的大大告知一下~
或许以后的新车款会加一个Touch ID、Face ID 来取代钥匙或是做为两阶段验证用
如果Apple 以后真的造了车，一定要把Touch ID 加上去呀~
