Theoretical notion of white-box

Is there any theoretically safe notion of white-box? I have been reading about white-box [1, 2, 3] recently. It seems white-box deals with code obfuscation and its not known whether a perfect white-box exists. I am curios about theoretical notion…

What's the point of hiding the key in white box cryptography if the attacker already has full access to the encryption (or decryption) implementation?

The attacker doesn't need the key in order to decrypt ciphertexts or encrypt plaintexts since he/she already has the full implementation. So what's the point of hiding the key? What advantage would the attacker even have by knowing the…

Whitebox AES: why not steal the whole whitebox?

If I understand correctly, Whitebox AES is a way of transforming decryption code to make impossible to recover the decryption key, even if you have access to the code. But what's stopping someone from just separating the entire whitebox decryption…

Software Security Impossible in Non-Trusted Hardware?

Fundamentally it is impossible to protect software if you can't trust the execution platform (e.g. using a TPM), so what is the point of software security then? With vendors claim that their white-box crypto / obfuscation technique are the best, is…
