r-irbe Data & Information Security
Formal foundations of security properties, access control, information flow, privacy, and their verification in formal frameworks.
Routing
- USE FOR: Data security and information security formalization — CIA triad, access control models (BLP, RBAC, ABAC), information flow, cryptographic primitives, privacy (differential privacy, k-anonymity), threat modeling, and their formal verification in Lean 4. Use for security properties of provenance chains, trust composition, and multi-agent systems.
- DO NOT USE FOR: Lean formalisation of these policies (use @lean-security-formalization); engineering disciplines more broadly (use @applied-engineering-disciplines); legal-policy reasoning (use @applied-legal-reasoning).
- TRIGGERS: CIA triad, access control, BLP, RBAC, ABAC, information flow, cryptographic primitive, data security.
Workflow
- Classify the security goal in the CIA triad and pick the access-control model (BLP / RBAC / ABAC) or information-flow model (non-interference) from the body.
- Apply the chosen model to the concrete asset or flow; surface assumptions and gaps.
- Produce the security argument or policy ready for formal encoding.
- Hand off: to
@lean-security-formalizationfor the Lean encoding, to@applied-engineering-disciplinesif reliability/safety overlap, to@lean-zettelkasten.
Recovery & STOP
- STOP if the question demands a Lean proof — delegate to
@lean-security-formalization. - STOP if the question is about cryptographic-protocol design — escalate to
@research-councilif the body lacks the protocol. - STOP if the question is about legal/regulatory compliance — delegate to
@applied-legal-reasoning.
