UBITECH, CASTOR’s project coordinator, presented its latest paper, titled “Slice & Dice: Privacy-Preserving Layered Attestation via Active Memory Introspection,” at SECRYPT 2026.
The work addresses the limitations of static binary load-time checks by introducing an active memory introspection architecture, where a minimal firmware layer can dynamically monitor runtime memory for modifications affecting the code integrity of trusted application workloads. By combining active introspection with Zero-Knowledge Proofs (ZKPs) and BBS anonymous credentials, Slice & Dice enables continuous, real-time remote attestation without exposing sensitive hardware or workload metadata.
This privacy-preserving, multi-layer trust mechanism is directly relevant to CASTOR’s work on trusted path routing. It can support the dynamic verification of node integrity and platform health along network paths, while preserving confidentiality across heterogeneous and multi-domain infrastructure.
