So Intel have added a so-called On-Die Certifying Authority (ODCA) with ME gen 3 version 15 based platforms.
That is also explained in the recent CSME whitepaper.
I figured that the FTPR CPD manifest contains a new extension now for certificate revocation, including a URL to CRL data.
That extension's data itself is encoded as ASN.1 DER, so I need yet another parser. Uh-oh... which one should I choose, does anyone have recent experiences to share? 🙃
I am checking t…

From Covid-19, we learned that a somewhat coordinated global response is (would be) required, because people travel. Forget about that under the Trump regime and his antivaxx buddy RFK jr.
This will first hurt Americans, but in Europe, we're bound to feel the impact too.

Today I learned a new word (or pair of words): "executive physical".
In other words, medical care for the wealthy and powerful, but not for us peons.

TESS Discovers a Second System of Transiting Exocomets in the Extreme Debris Disk of RZ Psc
We present the TESS discovery of only the second system of transiting exocomets with a sufficient number of events to measure the size distribution in the RZ Psc system, enabling comparisons with the $β$ Pictoris and Solar System size distributions. Twenty-four transits with absorption depths (AD) of 1--20\% were observed across three TESS sectors of the 20-50 Myr K0V star, detected as part of our TESS survey of extreme debris disks identified by their IR excess. We discover that the ADs (and …

Learning with errors may remain hard against quantum holographic attacks
The Learning with Errors (LWE) problem underlies modern lattice-based cryptography and is assumed to be quantum hard. Recent results show that estimating entanglement entropy is as hard as LWE, creating tension with quantum gravity and AdS/CFT, where entropies are computed by extremal surface areas. This suggests a paradoxical route to solving LWE by building holographic duals and measuring extremal surfaces, seemingly an easy task. Three possible resolutions arise: that AdS/CFT duality is intr…

A laser with instability reaching $4 \times 10^{-17}$ based on a 10-cm-long silicon cavity at sub-5-K temperatures
The realization of ultra-stable lasers with $10^{-17}$-level frequency stability has enabled a wide range of researches on precision metrology and fundamental science, where cryogenic single-crystalline cavities constitute the heart of such ultra-stable lasers. For further improvements in stability, increasing the cavity length at few-kelvin temperatures provides a promising alternative to utilizing relatively short cavities with novel coating, but has yet to be demonstrated with state-of-the-a…

Spectral Control of a Cavity-Based X-ray Free-Electron Laser via Active Mode Locking
Precise spectral control in the hard X-ray regime remains a long-standing challenge that limits applications in atomic-scale science and ultrafast spectroscopy. We present an actively mode-locked cavity-based X-ray free-electron laser that achieves deterministic spectral programmability with phase-locked pulse trains and comb-like spectra, by coherently modulating the electron-beam energy. Three-dimensional time-dependent simulations predict \SI{700}{\micro\joule} total energy, \SI{30}{\giga\wa…
