Why it matters: This article is crucial for engineers working on security, privacy, and identity systems. It highlights the urgent need to integrate post-quantum cryptography into Anonymous Credentials to protect against future quantum attacks and ensure privacy in digital identity solutions.
- •The internet is migrating to post-quantum (PQ) cryptography, a complex transition requiring new, higher-cost algorithms like ML-KEM and ML-DSA, not simple drop-in replacements.
- •Anonymous Credentials (ACs) are vital for privacy, enabling attribute proof without over-sharing, but current AC schemes are vulnerable to quantum attacks.
- •Digital identity systems, like the EU wallet, need robust unlinkability for privacy; PQ-safe ACs offer a cryptographic solution superior to organizational policies.
- •The "store-now/harvest-later" threat necessitates urgent development of PQ-safe ACs to ensure their long-term viability and prevent obsolescence upon mass adoption.
- •While PQ TLS migration progresses, ACs present a greater challenge, demanding efficient PQ replacements or significant re-engineering for scale and privacy.
Why it matters: Engineers must understand that IP addresses no longer reliably identify single users due to CGNAT. Failing to detect large-scale IP sharing can lead to unintended collateral damage, disproportionately affecting users in developing regions and causing significant operational and security issues.
- •Traditional IP-based security mechanisms (blocklists, rate-limiting) assume a single IP represents a single user, an assumption no longer valid due to widespread CGNAT, VPNs, and proxies.
- •Carrier-Grade NAT (CGNAT) allows ISPs to share a single IPv4 address among hundreds or thousands of users, primarily driven by IPv4 address exhaustion, especially in developing regions.
- •This large-scale IP sharing creates significant collateral damage, leading to socioeconomic bias where security actions disproportionately affect users in regions with high user-to-IP ratios.
- •Cloudflare is developing methods to detect large-scale IP sharing to mitigate unintended negative impacts and improve digital equity, a problem recognized by IETF RFCs.

Why it matters: This article introduces A-SFT, a novel post-training algorithm for generative recommenders. It addresses key challenges like noisy reward models and lack of counterfactual data, offering a practical way to improve recommendation quality by better aligning models with user preferences.
- •Generative Recommenders (GRs) model user behavior as a sequential transduction task, inspired by transformer architectures.
- •Applying RLHF to GRs is challenging due to the lack of counterfactual feedback and the inherent noisiness of recommendation reward signals.
- •User feedback is on-policy, making it impractical to obtain evaluations for hypothetical or unseen recommendations.
- •Reward models in recommendation systems often exhibit high uncertainty, as user choices are less structured and more random than language data.
