It outlines MOLE, a developing anonymous-credential design, and a candidate blind-signature construction measuring 4.3 KB. For AI builders operating public services, the implication is architectural rather than immediate: quantum migration may change protocol and capacity design, not just the cryptographic algorithm.","published_at":"2026-11-06","updated_at":"2026-11-06","record_date":"2026-11-06","date_kind":"published_at","topics":["security"],"entities":["Cloudflare","Privacy Pass","MOLE","VOLE-in-the-Head","UOV","PoMFRIT","ML-DSA-44","iCloud Private Relay"],"related_patterns":[],"novelty_label":"new_fact","what_changed":"Cloudflare introduces post-quantum privacy protocols for Privacy Pass, including MOLE and VOLE-in-the-Head, addressing privacy protections beyond its earlier post-quantum security work.","prior_refs":["https://newruntime.com/posts/bringing-post-quantum-cryptography-to-geographically-fenced-key-507697/"],"source_url":"https://blog.cloudflare.com/vole-mole","source_urls":["https://blog.cloudflare.com/vole-mole"],"schema_version":"newruntime-agent-readable-v0.2","stable_id":"post:the-post-quantum-future-of-web-privacy-ffbe79","status":"published","visuals":[],"editor":{"role":"editor","name":"Andrey Reshetnikov","profile":"https://newruntime.com/owner-profile.md","profile_json":"https://newruntime.com/owner-profile.json","same_as":["https://www.linkedin.com/in/reshetnikov1/","https://t.me/lapetuse"]},"routes":{"html":"https://newruntime.com/posts/the-post-quantum-future-of-web-privacy-ffbe79/","markdown":"https://newruntime.com/posts/the-post-quantum-future-of-web-privacy-ffbe79.md","json":"https://newruntime.com/posts/the-post-quantum-future-of-web-privacy-ffbe79.json"},"markdown_url":"https://newruntime.com/posts/the-post-quantum-future-of-web-privacy-ffbe79.md","next_reads":[{"type":"topic","path":"/topics/security/","url":"https://newruntime.com/topics/security/","title":"Security","reason":"Explore the security topic hub.","media_type":"text/html","markdown_url":"https://newruntime.com/topics/security.md","json_url":"https://newruntime.com/topics/security.json"},{"type":"collection","path":"/posts/","url":"https://newruntime.com/posts/","title":"Field Notes","reason":"Open the latest editorial analysis.","media_type":"text/html","json_url":"https://newruntime.com/posts.json"},{"type":"collection","path":"/sources/","url":"https://newruntime.com/sources/","title":"Sources","reason":"See the original sources this archive cites.","media_type":"text/html"}]}
