in truth

there is no security without hw enforcement (like wintel), so it becomes when 
does Android have securiity and can be trusted with valuable info
if we agree cloakware-like is not going to be strong enough... and the open 
model is too risky

at present to make apps run and have people have fun with new apps, with a vail 
of trust, hope you can trust the source of the app

lets protect:
personal info (killer App #1 for security)
financial info, no one will put banking info on Android if they have $$$, or 
will do special bank account with no money < 1k$, other...
DRM...  (dead by now)

Corp IP (email, ... worth much more), if an IP company (like  ....
can't allow an Android phone mobile device if no real security, hw enforced

is there a process to address this in Android, otherwise it is fun but not...

imho

I would imagine that it would be supported at some point, but there is no 
schedule at this point.

OK, if not require, then will the usage of HW security be supported?

All

asked this some time ago and it may not be changing

will future versions of Android require hardware features for support of 
security:

Trustzone like secure virtualization of the processor execution environment
OTP internal data storage for one time programmable keys or identity
Crypto Acceleration (AES, SHA, RSA, ECC,...)

is this planned or discussed for future versions


thank you

There are no guarantees about how secure a device is without ro.secure being 
set -- at this point only devices with it set have been shipped, so there 
hasn't been a security review for the system running without it set.  I doubt 
any one person actually knows what all is impacted by not having it set.

As far as carriers, the big one is giving the user root access.  Sure, if you 
have ro.secure not yet, then the user can get root access...  but because this 
configuration hasn't been productized, there are some potentially disturbing 
repercussions such as the fact that all you need to do is leave adb access on, 
and anyone can plug your phone into a computer and have root.  If a 
non-developer phone is going to ship without ro.secure set, at the very least I 
think it would be required to have a facility to set a root password.

Bottom line: if you are going to ship a device without ro.secure set, be sure 
to examine all of the code that this impacts to make sure you are okay with the 
result.

Doesn't the setting of ro.secure depend on his needs? (At least, the engineers 
on IRC are always claiming that the "proper" android setting is off and it is 
the evil carriers who insist on turning it on, etc.) Turning it on may be the 
right answer but it doesn't seem like it is the only one.

When you are creating the user image for your device, you need to sign 
everything with your own private keys that nobody else has access to.  You also 
need to make sure the ro.secure system property is set, and that the build 
phase for generating the final dexopt files into the system image is done (so 
dexopt doesn't need to be run at boot).

This is the "mydevice-user" configuration.  Generally development will happen 
with "mydevice-eng" or "mydevice-userdebug", but the result of these build 
configurations is not intended for shipping on a device.

The security keys under the directory android\build\target\product
\security is used to sign the apk for defferent security level. do
they need to generate some new keys of theirself or do not change it
for some compatible problems?

thank you
