Classical Acceptance Is Not Hybrid Authentication: Measuring X.509 Verifier Semantics in Post-Quantum Migration

Abstract: A relying party validating a hybrid X.509 certificate --- carrying both a classical and a post-quantum credential --- must distinguish whether its accepting judgment rests on the post-quantum evidence or only on the classical path. To preserve compatibility, the separable designs place that evidence where classical path validation may ignore it. A verifier can then validate the classical path and accept while the post-quantum evidence never bears on the decision --- a valid classical result silently promoted to a hybrid conclusion it did not establish. We measure this across eight path-validation stacks (seven independent codebases), in nine validation modes, over six certificate schemes. Under a hybrid-required policy, nearly every stack parsing a separable hybrid certificate accepts on the classical path without making the post-quantum evidence outcome-bearing; one enforcing mode instead fractures interoperability over a signature-input encoding not yet interoperably profiled; and stacks that verify post-quantum signatures still do not enforce the binding by default: the gap is structural, not explained by missing primitive capability alone. Under lifecycle desynchronization the downgrade is realized: when a bound post-quantum credential is revoked while the classical certificate stays valid, the default path still accepts, because the bound credential lies outside the decision's scope. Binding success is not authentication success. We contribute a specification-derived verifier model and an executable, policy-parametric reference contract --- what a verifier must recognize, verify, make outcome-bearing, and check before reporting a validation as hybrid --- with a diagnosis of why standards do not require it.

LFI est devenu une milice organisée ? Ca plus l'assassinat du militant fasciste.. S'ils ne veulent pas être considérés comme un parti extrême il faudrait nous montrer un peu mieux qu'ils ne le sont pas..
Ça me rappelle la montée au pouvoir du parti d'Hitler, les partis de gauche Š l'époque avaient décidé que leurs ennemis étaient les autres partis de gauche et non pas l'extrême-droite du coup ils se sont entre-détruits et le parti nazi n'a plus eu qu'Š ramasser les miettes (même s'ils …

Abstract: We design a reflective scatterer that operates only in the backscatter direction using modulation of the Kerker effect. This being a phenomena where the resonant modes of a scattering object produce total destructive interference in the backscatter direction. Our design consists of a dielectric shell and an interior metal element that provide the required dipolar contributions for Kerker interference with angular stability. By incorporating a PIN diode, we obtain a scatterer that exhibits strong amplitude modulation in the backscattering direction that is weaker at other bistatic angles. Backscatter modulation is a key technology to connect everyday objects but can be vulnerable to eavesdropping, the device presented in this work may help guard against such flaws.

I Can See the Babies
---
Whenever I see a person, my mind automatically conjures up an image of them as a baby. It's not really voluntary, nor is it the same as other mental imagery. More like I'm hallucinating a visual echo of their past self, floating in my vision near where I see the person. As if they were haunted and I could see the ghost.
It's all in my head, I'm pretty sure, and the babies aren't necessarily accurate. I checked once with a friend, and the baby I saw had curly hair even though all their baby pictures were bald. After seeing those pictures, my baby image of them changed, too, to match the pictures. So that's why... That's why I'm pretty sure...
But the babies are real, you know? I mean, my images of them might not be right, but all the people I see *were* babies. It's not like one of those stupid prophecy loopholes like "everyone was born of woman", you see, it's a true universal, no exceptions. And these hallucinations won't let me forget about that. Ever.
I tried to play a videogame once, one of those FPS games. My friends were all playing and they needed one more for their group. They didn't know about... this. I told them I didn't think I could do it, but I didn't want to tell them why, so they badgered me into it. I thought maybe I could handle it, I mean the characters were basically cartoons, right? But... well, I think I dissociated a bit and then threw up. Even if they were cartoons, all those babies, shooting and killing and dying, again and again. It's... it's not like the babies got injured, even, or played out exactly what the characters were doing. The babies just kinda floated around doing baby things, and they sort of faded out when their character died. No, what's overwhelming is the knowledge, the constant reminder, of everyone's former innocence.
The worst part, you know, the most horrible thing, is not just the innocence, it's the gap. Like, if you were to force me to watch a torture scene, I would hate seeing the victim, but it's the torturer that scares me. Everybody knows that horrible things happen to innocent people. We're all forced to think about that from time to time. But the thing almost nobody thinks about as much as me, is how innocent babies *become* monsters. How there's a hurricane of hurt and fear and apathy and indoctrination and hatred and prejudice and complicity out there that sucks in babies and twists them into racists and abusers and "business leaders" and soldiers and all sorts of people who hurt and kill others. The worst are the ones who take pleasure in that hurting, because the babies for sure don't. Like, how did that happen? And most people don't think about it, because they just label that person as "bad" and don't think about it any deeper. But you can't do that when you can see the baby right there. The baby isn't bad. The person might be, I'm not trying to say everyone's an angel or people don't deserve to reap what they sow. But the baby wasn't! Something between then and now went wrong, horribly wrong, and now you're stuck with a person that hurts others, and you need a drastic intervention just to stop them, let alone prevent them from doing that stuff again and change their future behavior. But you can *see*, or at least, I can see, that there was always some earlier point, some missed opportunity, where some much easier intervention could have headed the whole thing off. None of those babies are destined to turn into monsters, and that's the gap. The gap between the little baby that was and the monster in front of you on the screen or in real life.
Anyways that's it. That's my statement. I'm not a pacifist or anything, but I think you can see why I can't do it, I just can't. You can lock me up or punish me or whatever, but there's just no way you're gonna put a gun in my hands and give me an order and I'll just follow it, because I can see the babies.

Interessante Begründung, O-Ton im Rendez-vous am Mittag gerade eben: "Weil der Bundesrat keinen Finger rührt, dürfen die Kantone in ihrer Gesetzgebung weitergehen."
Ob sich das auch andere Bereiche anwenden liesse, wenn der BR mal wieder die Arbeit verweigert. 🤔

“McConnell says
‘I didn’t have a heart attack or a stroke.’
But nowhere in the letter does he address the cardiac arrest,” Journalist Ken Klippenstein wrote.
“Swapping out ‘cardiac arrest’ for ‘heart attack’ is a clever move because most people use the two terms interchangeably.
They are not.”
Klippenstein went on to argue that McConnell's statement was a
"masterclass in political manipulation"
– technically accurate in denying he'd…
