If you’re hoping that we have an upgrade this time, here is his successor posting nonsense about a discussion he clearly didn’t understand and almost certainly wasn’t supposed to disclose:
Tweet from JD Work that says: “Becoming a casual observer to morning debates on theoretical limiting conditions for elliptic curves in variant manifold topologies reminds one of the vast gulf between application and policy in the hard problems of cyber operations.”

Hashing-friendly elliptic curves (Dimitri Koshelev) ia.cr/2025/1926
Abstract. This article aims to consider batch hashing to elliptic curves. The given kind of hash functions found numerous applications in elliptic curve cryptography. In practice, a hash-to-curve function is often evaluated at a time by the same entity at many different inputs. It turns out that under certain mild conditions simultaneous evaluation can be carried out several times faster than separate ones. In this regard, the article introduces a new class of elliptic curves over finite fields, more appropriate for multiple hashing to them. Moreover, two explicit hashing-friendly Montgomery/twisted Edwards curves (of  ≈ 128 security bits) have been generated: one of CM discriminant −7, i.e., a GLV-friendly curve and one of huge CM discriminant, i.e., a CM-secure curve. The new elliptic curves are intentionally covered by so-called Klein’s and Bring’s curves of geometric genera 3 and 4, respectively. The latter are well studied in various algebraic geometry contexts, although they have not yet been (reasonably) applied in cryptography to the author’s knowledge. Such a mathematical complication is justified, since conventional curves (from existing standards or of j-invariants 0, 1728) are seemingly less efficient for batch hashing.

Jewelweed is a herbaceous plant that grows 0.9–1.5 m (3–5 ft) tall. It often branches extensively. The round stems are glabrous (smooth) and succulent, and semi-translucent, with swollen or darkened nodes on some plants. The leaves, which measure up to 13 cm (5 in) long and 6 cm (2+1⁄2 in) across, are alternate on the upper stems and opposite on the lower stems (when present). The leaves are ovate to elliptic, simple, and have shallow, rounded teeth on the margins. The seed pods have five valves which coil back rapidly to eject the seeds in a process called explosive dehiscence or ballistochory. This reaction is where the name 'touch-me-not' comes from; in mature seed pods, dehiscence can easily be triggered with a light touch. The plant blooms from late spring to early fall. The flowers are 2–3 cm (3⁄4–1+1⁄4 in) long, orange (sometimes blood orange or rarely yellow) with a three-lobed corolla; one of the calyx lobes is colored similarly to the corolla and forms a hooked conical spur at the back of the flower. Plants may also produce non-showy cleistogamous flowers, which do not require cross-pollination. Nectar spurs are tubular elongations of petals and sepals of certain flowers that usually contain nectar. Flowers of I. capensis have these nectar spurs. Nectar spurs are thought to have played a role in plant-pollinator coevolution. Curvature angles of nectar spurs of I. capensis are variable. This angle varies from 0 degrees to 270 degrees. The angle of the nectar spur is very important in the pollination of the flower and in determining the most efficient pollinator. Hummingbirds are major pollinators. They remove more pollen per visit from flowers with curved nectar spurs than with perpendicular nectar spurs. But hummingbirds are not the only pollinators of I. capensis. Bees, especially bumblebees play an important role in pollination as well. Due to hummingbirds and bees, the pollination of I. capensis is very high.

qt-Pegasis: Simpler and Faster Effective Class Group Actions (Pierrick Dartois, Jonathan Komada Eriksen, Riccardo Invernizzi, Frederik Vercauteren) ia.cr/2025/1859
Abstract. In this paper, we revisit the recent PEGASIS algorithm that computes an effective group action of the class group of any imaginary quadratic order R on a set of supersingular elliptic curves primitively oriented by R. Although PEGASIS was the first algorithm showing the practicality of computing unrestricted class group actions at higher security levels, it is complicated and prone to failures, which leads to many rerandomizations. In this work, we present a new algorithm, qt-Pegasis, which is much simpler, but at the same time faster and removes the need for rerandomization of the ideal we want to act with, since it never fails. It leverages the main technique of the recent qlapoti approach. However, qlapoti solves a norm equation in a quaternion algebra, which corresponds to the full endomorphism ring of a supersingular elliptic curve. We show that the algorithm still applies in the quadratic setting, by embedding the quadratic ideal into a quaternion ideal using a technique similar to the one applied in KLaPoTi. This way, we can reinterpret the output of qlapoti as four equivalent quadratic ideals, instead of two equivalent quaternion ideals. We then show how to construct a Clapoti-like diagram in dimension 2, which embeds the action of the ideal in a 4-dimensional isogeny. We implemented our qt-Pegasis algorithm in SageMath for the CSURF group action, and we achieve a speedup over PEGASIS of 1.8× for the 500-bit parameters and 2.6× for the 4000-bit parameters.

NEW: Blockchain monitoring firm Elliptic says North Korean hackers have stolen more than $2 billion in crypto this year, an all-time record, with three more months to go.

The estimate is based on more than thirty hacks against crypto exchanges and also “high-net-worth individuals.”
