Windows 7: RSA 1024-bits Key Encryption Cracked

RSA 1024-bits Key Encryption Cracked

Basically, we're not longer safe!

In summary, instead of using brute force, they stressed the processor containing the authentication key by submitting it to voltage stress. Subsequent errors allowed scientists to reconstitute the key. This information comes couple of weeks after some scientists successfully cracked by brute force attack in 2.5 years a 768-bits encryption key. The way to avoid such stress-based attack would be to modify CPU to make them insensitive to such voltage variation. Now, the next protection level would be 2048-bist encryption..

I don't know how big a deal this really is.

You have to have acess to the machine that the person is trying to connect too, and you would only crack the key he is using for THAT machine.

Basically you would have to break into a banks computer system /physically/ to perform this test to inercept and decrypt communication from a persons machine to THAT computer only. There are probably far easier ways of getting that info if you "own" the machine at that point.

The only serious danger is if that key can be cracked externally which it hasn't yet. (2.5 years for a key abtou a billion times less secore)

The shock isn't in the vulnerabilities. It is more about the new process for cracking the 1024-bit encryption and in such a short time.
