The main innovation addresses two problems: noise building up in encrypted feedback loops and the slowness of doing complex nonlinear operations (calculations that don't follow straight-line relationships) on encrypted data. ENClose uses techniques like function segmentation and tree-based selection to speed up these encrypted calculations by 3 to 20 times compared to previous methods, as demonstrated in real-world tests like vehicle formation control and anomaly recovery.","solution":"N/A -- no mitigation discussed in source.","labels":["research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11480182","publishedAt":"2026-04-14T13:17:13.000Z","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":"2026-04-14T13:17:13.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["confidentiality"],"aiComponentTargeted":null,"llmSpecific":false,"classifierConfidence":0.75,"researchCategory":"peer_reviewed","atlasIds":null}}
