# Senior Cryptographer Activity Tracker — RSA Factoring Engagement 2024-2026 (as of 2026-05-08)

The atlas has documented **30+ senior cryptographers** with effectively zero factoring-direct output during the 2024-2026 window. This silence is itself a structural finding — the field's leadership has migrated wholesale to post-quantum, isogeny, FHE, MPC, lattice, election-security, and policy registers. This tracker converts that silence into a queryable, audited record. Each entry is held against an explicit **trigger condition** that would invalidate its silence classification.

> *"There's not been any cryptographic success made by AI."* — Adi Shamir, RSAC 2026 Cryptographers' Panel
> *"If you need to keep secrets for 100 years, don't use today's RSA."* — Adi Shamir, RSAC 2024

**Tier legend.** A = active on factoring; B = pivoted away; C = curatorial; D = silent / classified pattern; E = silent / topic shift.

---

## Tier A — Active on factoring (rare)

The full publicly active 2024-2026 surface for classical balanced-semiprime factoring fits inside three groups + a few isolated authors. Everyone else is in Tiers B–E.

### Nadia Heninger — UCSD
- **Last factoring-direct paper**: Bäumer-Heninger SSH signature batch GCD (CCS 2025); Davis-Green-Heninger-Ryan-Suhl Micali-Schnorr backdoor (eprint:2024/304); Bleher-Chinburg-Ding-Heninger-Micciancio Voronoi rings of integers (arXiv:2512.19518).
- **2024-2026 status**: only senior PI with a continuous factoring-adjacent pipeline; PhD line (Keegan Ryan, EUROCRYPT 2025 multivariate Coppersmith) lands in Bill 4.
- **Activity domain**: factoring (batch GCD / Coppersmith / lattice) + systems security (RADIUS, AirTag, GEO satellites).
- **Public statements**: UCSD CSE 207B Fall 2024+2025 lectures still teach RSA-250 as the canonical record.
- **Significance flag**: only Tier-A node with first-author factoring-direct output 2024-2026.
- **Trigger**: Heninger silent for 12 months consecutively → reclassify B.

### Caramba team — Inria Nancy (Gaudry, Thomé, Joux-adjacent infrastructure)
- **Last factoring-direct paper**: CADO-NFS RSA-250 (2020); Fleury PhD *Amélioration des algorithmes de crible* (Paris-Saclay 2024, advisor Gaudry); Kirchner PhD (Rennes 2025, advisor Fouque/Lercier — RSA-250 sieving analysis).
- **2024-2026 status**: 2025 Levchin Prize for CADO-NFS — *capstone, not continuation*. Senior members pivoted to isogeny (Gaudry-Soumier-Spaenlehauer eprint:2025/136) and DLP (Thomé Discrete Logarithm Factory).
- **Activity domain**: factoring (PhD pipeline only) → isogeny + DLP + e-voting.
- **Significance flag**: Levchin Prize is explicitly a *cap* on the team's RSA work.
- **Trigger**: any new Caramba-authored RSA-bit-record arXiv submission → A reaffirmed.

### Feng-Nitaj-Pan-Zheng cluster (RSA-variant Coppersmith)
- **Last factoring-direct paper**: continuous flow into Bill 4 — RSA-variants, Boneh-Durfee improvements, partial-key-exposure papers throughout 2024-2026 (TCS Vol 994, Vol 1004, Vol 1057, IWSEC 2024, JMC 2024).
- **2024-2026 status**: most prolific Bill-4 trigger cluster outside the Heninger group; explicitly works on *RSA variants* (CRT-RSA, Prime Power RSA, Multi-prime, Murru-Saettone, KMOV) with structural weaknesses, not balanced semiprime.
- **Activity domain**: lattice / Coppersmith on RSA-variants.
- **Significance flag**: keeps Bill 4 hot; never crosses into balanced-semiprime threat.
- **Trigger**: any cluster paper claiming sub-Coppersmith bound on *balanced* RSA → A reclassified to gate-claim probe.

## Live signal

> **If any Tier-D researcher publishes an original factoring algorithm 2026+, that's a Tier-A reactivation event and warrants immediate atlas update.**

Highest-leverage reactivation candidates (in descending order of corroborating evidence weight):

1. **Don Coppersmith** — Bill 4 namesake; classified-pattern silence; any unclassified output is a maximal signal. (Trigger: arXiv / IDA white paper / talk slot at Crypto/Eurocrypt.)
2. **Ron Rivest** — RSA 50th anniversary in Aug 2027; pre-anniversary 2026 retrospective would itself be a signal even without algorithm content.
3. **Hendrik W. Lenstra Jr. or Arjen K. Lenstra** — curatorial pivot is firm; any return to original algorithm-construction would invert the field's read of the era.
4. **John Pollard** — any public communication.

Atlas pipeline action: round-by-round arxiv_deep_loop scans pre-emptively check for these names; a hit opens a fresh paper-card and triggers the Tier-A reclassification audit.
