{"data":{"id":"5ccd4da0-536e-4424-94f2-482498aee84b","title":"Updatable Multi-Party Private Set Intersection for Real-Time Collaborative Threat Intelligence","summary":"This research presents a new protocol called Updatable MPSI (UMPSI) that helps multiple organizations securely share threat intelligence data while keeping their information private. Unlike existing systems that require expensive full re-computation when threat data changes, UMPSI uses lightweight mechanisms to quickly update only the new or changed threat indicators, making real-time collaborative threat detection practical.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11579414","publishedAt":"2026-06-25T13:17:25.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"research","affectedPackages":null,"affectedVendors":[],"affectedVendorsRaw":[],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":"2026-06-25T13:17:25.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["confidentiality"],"aiComponentTargeted":null,"llmSpecific":false,"classifierConfidence":0.72,"researchCategory":"peer_reviewed","atlasIds":null}}
