Instead of traditional keys, the system uses temporary credential tokens issued by multiple authorities, and it uses lattice-based cryptography (a math method believed to be secure even against quantum computers) to ensure that both credentials and access policies cannot be forged.","solution":"N/A -- no mitigation discussed in source.","labels":["research","security"],"sourceUrl":"http://ieeexplore.ieee.org/document/11516241","publishedAt":"2026-05-12T13:17:04.000Z","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":"2026-05-12T13:17:04.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["confidentiality","integrity"],"aiComponentTargeted":null,"llmSpecific":false,"classifierConfidence":0.72,"researchCategory":"peer_reviewed","atlasIds":null}}
