Comprehensive threat analysis across cryptographic, identity, delegation, network, and availability domains. Every attack vector has a concrete mitigation.

LOWEdge
Key Compromise
CRITICAL
VectorPrivate key extraction
MitigationSealed storage (Secure Enclave, kernel keyring). ZeroizeOnDrop on all key material.
VectorMemory scraping
MitigationConstant-time operations. No key material in logs. Zeroize on drop.
VectorSide-channel attacks
MitigationNo branching on secret data. Constant-time Ed25519 implementation (ed25519-dalek).
Identity Spoofing
HIGH
VectorDID impersonation
MitigationDID is derived from public key. Impersonation requires the private key.
VectorLineage forgery
MitigationLineage proofs are cryptographically signed. HKDF derivation is one-way.
VectorDocument tampering
MitigationJCS canonicalization + Ed25519 signature. Any modification invalidates the proof.
Delegation Abuse
HIGH
VectorPrivilege escalation
MitigationNo-amplification rule: child capabilities are always a subset of parent.
VectorStale delegations
MitigationTime-bounded tokens with mandatory expiry. No perpetual delegations.
VectorOrphaned agents
MitigationRecursive revocation. Revoking a parent cascades to all descendants.
Network Attacks
MEDIUM
VectorMITM on ceremony
MitigationNoise XX encrypted WebSocket. Mutual authentication via HMR DIDs.
VectorDHT poisoning
MitigationAll DHT entries are self-signed. Unsigned or invalid entries are rejected.
VectorReplay attacks
MitigationNonce-based challenge-response. Timestamp validation with clock skew tolerance.
Availability
LOW
VectorDHT eclipse attack
MitigationMulti-path resolution. Local cache fallback. Offline verification always works.
VectorCeremony denial
MitigationIdentifiable abort with blame. Misbehaving participants are excluded.
VectorResolution failure
Mitigation2-level cache (LRU + Redis). Sub-10ms p95 for cached lookups.
