(Note for lookup tables: This is indeed feasible because there are certain ranges within which the vast majority of primes(?) used in crypto are). I guess that their success rate will be quite shocking. germany) even openly state that they also want to crack and eavesdrop, will build or have systems with both, large lookup tables and very elaborate primeness checking. It is therefore reasonable to assume that most of the “cyber protection agencies”, some of which (e.g. There are quite a few out there who limit themselves to rather superficial checking. Bernstein/Lange demonstrated, a good level of primeness testing is required and unfortunately often not done. On the other hand that’s less of a problem than it might seem and for most purposes a “very likely prime” is good enough, because to make use of eventuall not really primeness requires the opponent to fully and extensively check somewhat less than 1/2 of the space for any given prime(?) number – which again would mean that our prime(?) already served its purpose.īut still, as i.e. The problem being that, to be certain, one needs to basically do what the opponent is to do, namely to extensively und fully check for primeness. Indeed, and not at all funny, many if not most (large) primes used in crypto are “pnly quite probably” primes. If someone manages to produce a CPU equivalent to a Celeron or an A4 without any backdoors and even put it in a nice laptop, it will become an instant hit. #GOANYWHERE OPENPGP STUDIO EXPORT PUBLIC KEY EMPTY FULL#So now every CPU on the market will have a full range of NSA approved backdoors like Intel Identity “Protection” and ME or PSP and similar “features”, and AMD believe they will have the ability to compete with the better Intel offerings by establishing similar backdoors. But DASH isn’t widely used yet, with Intel’s vPro dominating the business PC market. DASH shares many features with vPro, such as the ability to wipe out or shut down remote PCs that may have been stolen. #GOANYWHERE OPENPGP STUDIO EXPORT PUBLIC KEY EMPTY PRO#The Pro chips have remote management and security features based on the DASH (Desktop and Mobile Architecture for System Hardware) standard, which is widely used in servers. Now they lost even that last advantage of theirs:ĪMD’s Pro chips are comparable to Intel’s vPro chips, which are popular in business desktops. If AMD had something on their side, it was the lack of vPro backdoors.
