There are lots of math tricks used - NSA employs many PhD mathematicians.

 

 

or should I have said "many, many"

A useful attack on RSA would have severe implications.

Anything more efficient than brute force?

 

Quantum computing isn't anywhere close to being useful.

 

There are several algorithms that seem to be useful, yes.

Just finished Neil’s book. Tons to discuss September 9, 2019, the publication date. 

It's now the 10th.

 

What happened, or is the discussion in an area regular members don't have access to?  Or am I blind?  lol

why not send a FOIA Request to the NSA for the algorithms and ways to parse things, then crack...

I wanted to do it right, so I took my time. Here you go.

 

 

 

Thanks!  I was starting to wonder if the release date had been pushed back!  :D  Going to read your review now!

That seems to require a quantum computer that doesn't exist.

 

No just a fast PC - like the new Ryzen with the expensive GPU that can be used for calculations

Are you seriously suggesting that there exists a practical attack on RSA with a key length of 2048 bits or more? On a PC at that. You're either mistaken or trolling.

I really don't know how to troll - seriously. It is basic brute force. 

 

I joke yes, troll no.

Then mistaken or making an obscure joke. The entire point of Shor’s algorithm is that it's mathematically proven to offer a speedup on a quantum vs. regular computer.

 

Current estimates I've seen put cracking by brute force somewhere in the 2030 time frame, and I don't know whether that's dependent on quantum computing having become practical by then.

 

Far better possibilities are improved algorithms (that can be run effectively on non-quantum computers), or exploring vulnerabilities in badly constructed keys or key pairs.

Interesting anecdote about the reaction to a photo of a circuit board. Nothing I've published regarding MQA has received any response at all. Should I be jealous?


They did not even try to attack your MQA tools

How - as a VLC add-on, perhaps?

I don't think you should be jealous.  Any contact about anything you and I published about MQA would be seen as weakness on their part.   

 

Looking back at the timeline of MQA up til the posting of MQA is Vaporware, I am left wondering if Bob Stuart used Neil Young to get his funding for MQA.  But I just got Neil's book today.

The same thought on MQA came to mind reading Chris' review of Neil's book.  Maybe Stuart had it in mind, and the money from Mr. Young was how he started to put it in practice.  It fits with why it wasn't ready and everything else.  Sure would be ironic if Neil caused inadvertently for MQA to be finally born.
