SGX is a way of running security-sensitive user-mode code in an 'enclave'.Code running in an enclave has its memory encrypted and authenticated, and cannot beobserved by code running anywhere else. It's able to use device-specifickeys to encrypt ('seal') data to future executions of itself or enclaves signed by thesame key.

This project does PBKDF2 password hashing inside an SGX enclave.Password hashes are only available to enclaves which have been enrolled in a 'region',and therefore no amount of database leakage will jeopardise user passwords. Yourstack of GPUs are useless here.

A region is represented with a AES key, and enclaves in a region have a copy of itsealed to them. The key itself can be kept offline and only used when enrollingnew enclaves or doing disaster recovery.

See my corresponding blog post here.

Essentially, the random art generated by the user's keys can also be used in the same sort of way. If the image generated initially is different from the current image of the key, for example if you had moved a key, then the key had likely been tampered with, corrupted, or replaced. Nov 05, 2015  Summary: Ed Wilson, Microsoft Scripting Guy, talks about generating random letters with Windows PowerShell. Hey, Scripting Guy! I need to generate a string of random letters. These letters need to be five characters long, and they should be either upper case or lower case. Sensitive data, processes, and keys at runtime and create a trusted application environment To be equipped for a high security model (see Table 1), a device. Intel SGX technology to wrap application containers with a. Data High entropy source of random numbers to generate keys Intel® Advanced Encryption Standard.

Warning

This is extremely experimental. Use at your own risk. There is no warranty.

This repo includes a trivial region key, the enclave signing private key and the enclaveruns in debug mode, so this in fact provides no meaningful security.

• pwenclave/pwenclave.edl: defines the interface surface between user-mode code and the enclave.An Intel-provided tool takes this definition and generates stubs for calling these functions in user-mode and convertingarguments in the enclave (these are pwenclave/pwenclave_t.cand smoketest/pwenclave_u.c).
• pwenclave/pwenclave.c: implements this interface. There are bunch of other files alongside providing PBKDF2 etc.
• smoketest/smoketest.c: starts the enclave and exercises the functions.

'.join(random.choice(string.asciiuppercase + string.digits) for in range(N)) This is an excellent method, but the PRNG in random is not cryptographically secure. I assume many people researching this question will want to generate random strings for encryption or passwords. You can do this securely by making a small change in the above code.

• The Intel SGX SDK.
• Visual Studio 2012 (a prerequisite of the SGX SDK).
• The Intel SGX Platform Software (comes with SDK) along with SGX-supporting hardware (a Skylake CPU and working BIOS). The SDK supports a simulator; I haven't tried that.

As a fairly obvious result of all this, this is Windows only for the moment.

Once you've got all that sorted, you should merely be able to load the solution and hit run.
