With my mathematical bent, I'm less keen on prime numbers than the others. They just get in the way and clog up your calculations. So I've developed a little quirk over the years, like some enjoy their superstitions, I prefer to set the TV volume, etc, avoiding 13, 17, 19, 23, 29... Don't get me wrong, I don't break out in a sweat if it happens, it's just a bit of harmless fun. So 2023 has always grated a bit, that is until yesterday when I suddenly realised it's not a prime number after all, but the product of 7 x 17 x 17. So, I feel happier with it now.... better late than never, with just 12 hours left to run! Yes, I'm a bit crazy, but regular readers will already know that.  Wishing you all a happy, factorisable 2024. |

I have to admit that your idea of "harmless fun" leaves me even more worried about you than previously  Still, 2024 is going to be a great year.................but don't count on it. Happy new year bernie and everyone else.

I was so convinced that Ace, or someone else who likes numbers, would point out how 2027 will blow my mind (being a prime year), then I realised that, unlike me, those people probably have a life...

I was going to mention how 2027 might potentially be something of an annus horribilis for you but got side-tracked trying to calculate how excited you must be for 2048

Prime number are so important to all of us, being the basis of nearly all internet encryption. I have read about the basis of why prime numbers make such a strong encryption base but to be honest never have got a true understanding why. The idea of a public and private key I think I understand . Anyway what I want to say is prime numbers are all our friends without which the Internet could not exist in the way we all use it.

I was going to mention how 2027 might potentially be something of an annus horribilis for you but got side-tracked trying to calculate how excited you must be for 2048 2017, the year started lending bad loans, I don’t want to imagine what kind of future 2027and 2029 will hold. I wish all of you in 2024, the product of 2^3 X 23 X 11 will be a better year than 2023.

Sorry to disappoint. Nope, no life here, was just busy with my end of year report. The most exciting thing about the year end for me

Absolutely, at least until quantum computing has matured, whereupon brute-force cracking this type of encryption will be child's play. Here is probably the most easily followed description I've seen yet of the Diffie-Hellman key exchange protocol. The colour coding is especially helpful.

The colour coding is especially helpful. but why is it vulnerable to quantum computing ? I've often heard it said so, so I assume true. But I'm not sure why (given that QC doesn't de facto mean 'very very fast computing', but rather gives an ability to tackle problems in specific ways that means it can be in a different league, but only if the particular problem is amenable to QC'ing. Edit: OK, so I assume the answer is crystal clear and is reveavled in this link: linkHowever, I probably need to read it another day, not on December 31st at 22:15

I know very little about quantum computing, but from something I read, I believe it's to do with being able to process several similar strands simultaneously. This apparently lends itself perfectly to brute-force cracking, trying sequences of potential keys until hitting upon the right combination. This is currently an intractable problem with today's conventional computing, but will be cracked within minutes on a quantum computer, supposedly. EDIT: Lots of sources suggesting QC threatens encryption, but also a few saying not so. www.technologyreview.com/2019/05/30/65724/how-a-quantum-computer-could-break-2048-bit-rsa-encryption-in-8-hours/

I've actually just edited my post, but too late for you to capture in your quoting.
The link I've provided might be of interest. But not at this time of the day.
I have actually in a past life sat in on some useful and interesting education on QC. Plus as a physics graduate with a particular interest in QM I don't find the fundamental underlying concepts daunting. But if the relevant grey matter isn't being stimulated on a regular basis then of course it all sinks back into the quagmire of "Uhh, what ? I need to think a bit more"

Sadly with it being NYE I don't have the time right now.
