They propose SecDT+v1 and SecDT+v2, which use the transformation matrix technique to obfuscate attributes, and SecDT+vH and SecDT+vDP, which add dot-product operations to hide attribute access patterns. Evaluations on real-world datasets report better classification latency and bandwidth efficiency than prior solutions.","solution":"The paper proposes SecDT+v1 and SecDT+v2 (transformation matrix obfuscation of node attributes) and SecDT+vH and SecDT+vDP (dot-product operations to hide attribute access patterns) as enhancements to SecDT.","labels":["security","privacy","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11612923","publishedAt":"2026-07-16T13:16:28.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"low","attackType":["data_extraction"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":[],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-07-16T13:16:28.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["confidentiality"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":"peer_reviewed","atlasIds":null}}
