back to article RAND report finds that, like fusion power and Half Life 3, quantum computing is still 15 years away

Quantum computers pose an "urgent but manageable" threat to the security of modern communications systems, according to a report published Thursday by influential US RAND Corporation. The non-profit think tank's report, "Securing Communications in the Quantum Computing Age: Managing the Risks to Encryption," urges the US …

    Even if an iPhone had a quantum processor, it would still be a locked down piece of crap. I would still only be able to consume apps of a tiny uninovative store and I would still need to rent provision (DRM) profiles from Apple to run my own code.

    Basically, quantum computing will be useless unless it is "open". I don't even particularly mean "open-source". More like the IBM PS/2 compatible with a BIOS where we can do what we need to.

    Because of this, I don't think quantum computers will ever be owned by us "plebs". We will probably only ever be able to access their "benefits" via a stupid web browser.

      Even if an iPhone . . .

      What have iPhones or Apples to do with it? Also Apple is for people with money to spare. Us plebs buy $99 android phones and $400 laptops, some of the laptops run Linux.

      The PS/2 didn't have an open BIOS and was a failure in the market place.

      Real Quantum computers may or may not happen. Currently they need cryogenics, so even a "small" tower cased sized one might need a room full of support.

      Also Quantum computers are not simply faster computers. They handle specialised sorts of problems, so even if really useable ones ever exist you'd probably not want one.

      -

      Fusion power might be closer, it's hard to say. Basically unless there is a sort of working prototype of something any forecast is total guess work.

      Prototypes can take 6 months to 10 years to be commercial:

      See Passenger Jet Aircraft (idea is from 1938!). LED is 1924 or 1962. Radio 1898, but home in 1922. Electronic TV proposed 1905, working 1935. LCDs.

      Lithium cells nearly 20 years before used in phones and laptops.

        I used iPhone as an umbrella for consumption hardware. You think Android is more open? You still can't do anything on them but browse silly websites.

        The PS/2 compatible (compatible with PC/AT/XT) had 2 bios. One was "open".

        What I guess I was trying to say is that the quantum processor isn't important if we aren't allowed to do anything productive with it other than viewing adverts.

          Re: Even if an iPhone . . .

          The PS/2 used different I/O cards. MCA. It never had an open BIOS. Nor did the PC/XT/AT.

          The compatibles of the PC non-PS/2 systems didn't have an Open BIOS either. Compaq developed their own and the Phoenix BIOS a commercial clone supposedly created by a separate team reverse engineering the IBM PC BIOS (not PS/2) and issuing a spec. It was licenced. It was never open source at the time.

          https://en.wikipedia.org/wiki/Phoenix_Technologies#Cloning_the_IBM_PC_BIOS

          The IBM PS/2 was really the third generation IBM-PC. Unlike the first which used catalogue HW, IBM proprietary BIOS and MS's version of a reverse engineered CP/M-86, it had more proprietary HW and more IBM designing in it.

          "These models were in the strange position of being incompatible with the IBM-compatible hardware standards previously established by IBM and adopted in the PC industry. "

          The higher spec models were supposed to run OS/2, incompatible with DOS. The lower spec models were inferior spec to PC-AT clones at the same price, so despite about 3M corporate sales, the PS/2 was a failure. The PCjr even more so outside the USA.

          No PS/2 models could take the popular ISA expansion cards.

          Ironically the PS/2 came out the same year as the Archimedes running on ARM. 1987.

          PS/2 and OS/2 were too little, a couple of years too late.

            Re: Even if an iPhone . . .

            The PC BIOS was indeed open because in keeping with IBM documentation policy both the schematic for the computer and the assembler source for the BIOS were in the user manual. This is really what set the whole clone thing on fire -- anyone who could throw a PC board together and had a supply of the chips to make it was in the clone business. These halcyon days came to an abrupt end when IBM noticed the competition and sent a politely worded nastygram to the various manufacturers giving them a month to replace the BIOS. This resulted in a mad scramble to quickly code up a replacement -- not that difficult except that these early machines used a bunch of hardware specific gotchas to implement things like system calls so the result was 'compatible' but not necessarily 'identical'.

            Subsquent models of the PC were required to be software backwards compatible so essentially the difference between a PC, XT, AT and so on what was in what was added to support things like hard disks. Things like the audio casette interface (and eventually, ROM based BASIC) gradually disappeared since they were less than useful -- there's no point in cluttering up the address space with a language if you're not going to use it.

            (Luckily for everyone IBM's lawyers hadn't come up with the API copyright wheeze or we would have really been screwed!)

    Quantum vs COBOL

    Ok, so the US just might be vulnerable to encryption being cracked by quantum computing. Maybe. If there is usable quantum computing...

    The thing is, the really sensitive government stuff is protected by encryption that is not public. The problem is one for the rest of us out here, who are actually far more vulnerable to a chair and rubber hoses than encryption being broken by quantum computers. And because some mainframe back there is running COBOL, doesn't mean that it has information that is sensitive enough to warrant the expense of being cracked using a quantum computer.

    Current encryption is far more vulnerable to math and GPU attacks than the alleged eventual arrival of quantum computers.

      Re: Quantum vs COBOL

      "The thing is, the really sensitive government stuff is protected by encryption that is not public."

      Re: Quantum vs COBOL

      Quantum and COBOL is the obvious approach.

      Follow the path pioneered by CHAPS - all the complex message handling and protocol management was initially done on relatively slow Tandem NonStop fault-tolerant computers, which front-ended the member bank's mainframes. These undoubtedly did, and still do, run COBOL programs that handle all the bank's internal accounts and transactions. The Tandem machines used a very secure encription engine* which handled all outbound message encryption and inbound message decryption. The combination provides a secure, reliable gateway to the CHAPS financial network.

      This is a good way of handling security while maintaining network uptime and throughput. At the same time it keeps the internal systems well isolated from network nasties. Of course such a setup isn't cheap, but if manglement thinks its sensitive data doesn't justify the expense, then they deserve to carry the can if/when proved wrong.

      [*] This encrypt/decrypt engine could be quantum-based when, if ever, that technology achieves 99,99% uptime, something that Tandem NonStop systems and encryption engines achieved in the early '80s.

                        Most encryption will be applied automatically without you needing to provide a "key". The TLS handshake between your device and the server, and subsequent data encryption, will be transparent to the user. You might need to authenticate to some sites, so you'll need a "password ", and preferably a strong one...

                        Same applies to streaming services. A user might see no need for strong crypto, but a provider will!

    what is problem with COBOL ?

    who cares what language source code is written in ? As for underlying hardware, does it matter anymore outsiide of specialist cases like extreme conditions? What matters are human factors. PHB bean counters getting rewarded for cutting costs, not punished for not funding upgrades or determining if systems are still fit for purpose, secure and supportable. In short, a complete management and leadership failure. None of which matters has anything to do with languages. For the record, I like COBOL, verbose as it is but if properly written, it has three big benefits.

    (a) source code is documentation if variables are rationally named. Again, human factor.

    (b) Excellent control structures are mandated by language.. Again, code quality is created and maintained by humans.

    (c) The DATA section forces thought and understanding of the data types. This is where so much goes wrong.

    Would I use COBOL outside of business ? Probably not. C, Fortran or whatever is most suitable for problem, even if by some fluke a fashionable language might be a candidate.

            Wanting someone to define a complex idea in a single sentence is a sign that you really do not understand how definitions work. (Try defining "electricity" in a single sentence. Three quarter page sentences like the ones in a Thomas Hardy novel don't count.)

            Object orientation actually flows naturally from the SQLmodel of data, data flow diagrams, and scoping of functions just like we did in the 1970s. The problem in my experience is that spaghetti code programmers don't get it, regardless of age, because the ability to visualise a problem as blocks of functionality and data joined together by hooks of data flow and decision making is somewhat different from coding. For one thing, I think a degree of visual sophistication is necessary to design and understand architectures, and it's obvious that many programmers are very non-visual.

            I spent ages being suspicious of OO until I eventually discovered about 75% of it was IT SOP: wrap new words round what you've been doing all along.

            If you're programming in C you have a struct to define some data. If you're using SQL you have DDL to describe a table. At a design level you might have entities in an ER diagram. The extra bit with OO is that instead of having your struct and then free-floating functions you combine the two. Once you've got used to the changed vocabulary and the extra functionality it gives you you've added the next 24%.

            All you have to avoid is the 1% of the OO religious fundamentalists with the "everything's an object" approach. Stay pragmatic and it's simply another way of thinking about data and how to handle it. Sometimes you reach out for the set-oriented view of RDBMS and SQL, sometimes OO is what fits the job.

      Two things:

        I may be wrong, but it seems the fault tolerance can be adjusted by the provider. More mainstream sites that use them (like Patreon) seem to commonly let you through after one screen where more spammy sites (like less-reputed download providers) will force you through several of them. Whether it's due to honest false negatives or the system forcing you through it twice by wrongly saying you're wrong, I can't say. All I know is that they demand a lot more from you.

          Here in California you can't purchase alcohol at the self checkout. I solved that problem by making my own ... its hardly rocket surgery.

          On the bright side, it's not New Jersey where you have to go to a separate store to get alcohol. (Worse, they won't even let you pump your own gas/petrol in NJ. It's a good state to avoid.)

          Tip: Most "grocery stores" here in California have a Customer Service desk with a till. If you say PleaseAndThankYou and smile nicely, most stores will allow you to purchase up to 8-10 items from there, which means no queue to purchase a couple bottles of plonk ... One caveat, the CS till has no scales, so you can't buy anything not pre-labeled by weight there (meat, usually OK ... produce, not so much).

        "slow lines with human cashiers."

        The USA must be a strange place. Self service everywhere else in the world is faster for a couple of items, but only because of the lack of queueing. No way I'd scan a cart full of stuff myself when the cashier can do it 3-5 times faster.

        1. Charles 9

          Cashiers must be a whole other breed where you live because in most places the line is at the self-checkout because the cashier is slower than doing it your own damn self. Plus, with the whole Coronavirus business, less human contact is better, and self-checkout provides ways to minimize physical contact.

      What color is an Orange?

      True or False, adding two and two, adds up to five?

      True or False, False becomes before the word True in the dictionary?

      A computer does not understand context anymore than an image. Asking simple questions that rely on simple content/text versus math are at least as effective as ridiculous captcha's but far easier for humans to use...

      This is based on the computer science logic, that what is easy for humans is hard for computers, and what is easy for computers is hard for humans.

    15 years away

    Quantum computing will always be 15 years away, unlike fusion where you can turn towards the sun and feel the effects of real fusion happening. We just need to overcome the physical challenges of recreating, and crucially maintaining, the conditions at the heart of a star to generate more energy than you put in. With quantum computing you have to overcome the physical challenges of implementing wishful thinking that the right answer simultaneously coexists with all possible wrong answers and will magically pop out at you with enough funding.

    1. Andy1

      Re: 15 years away

      We have to do much better than reproduce the "conditions at the heart of a star". An article in New Scientist a long time ago said that Terrestrial fusion would have to be much denser than in the sun in order to generate any useable energy in a practical volume.

      1. Man inna barrel

        Re: 15 years away

        As far as I know, terrestrial fusion cannot achieve the densities that occur in stellar fusion. Magnetic confinement and so on cannot do the same job as gravity. The answer is to vastly increase the temperature over stellar values, so that slamming nuclei together overcomes electrostatic repulsive forces.

        1. Charles 9

          Re: 15 years away

          And gravity AIUI will only work over a certain critical mass. Basically, size is the main thing why something as big as Sol kicked off and something as big as Jupiter (which if you think about it is basically the same composition) didn't.

        I buttered a slice of toast on both sides, wrapped it in copper wire, attached the wires to a sort of hoop so the wires never get tangled, then dropped the toast to the floor.

        Because it can never land butter side up (it's against the laws of the universe), it just hovers above the floor constantly spinning like a gyroscope toy on speed. The electricity generated by the spin is transfered through the hoop & is captured, controlled, & consumed by all the gizmos in my house.

    The 2033 estimate is based on a "weighted average" of respondents. Which is fine if you believe the weighting coefficients chosen for the respondents. If you just take the median or even average (ignoring one low and one high)... well, that is a different story. The story is also different if you apply your own weighting. I prefer the AAS version.

    Finally, the RAND study is a sort of opinion piece, not really delving into the actual quantum computer developments but relying on a sort of filtered assessment by presumed experts. The weighting seems too heavy on academic folks, the ones dedicated to pumping out PhDs while fiddling endlessly with cash cow fusion.

    On the other hand, the discussion of various industry effects and impacts, and PQC, is worth reading if you into that sort of thing.

        The US public has been allowed to use whatever encryption we want. The restriction was on exporting simple math.

Later, I occasionally carried a copy of Bruce Schneier's "Applied Cryptography" book containing source examples in the text (which did not fall under the export restrictions) and the disk containing the very same source, which was bound into the cover (and very definitely did fall under those restrictions). Again, nobody even noticed.

        This kind of security theater isn't worth the paper it is printed on. Never has been, never will be. Won't stop the idiots in DC passing laws, though.
