Mutual TLS, SPIFFE Identity & Workload Attestation in ApiHSM
Securing cloud-native cryptographic access through cryptographic service identity attestation and hardware-backed mTLS.
Workload Identity Verification
ApiHSM validates incoming SPIFFE Verifiable Identity Documents (SVID), ensuring that only verified microservices running in designated Kubernetes namespaces can request signature generation from specific HSM keys.
Preventing Cryptographic Side-Channel Abuse
Built-in rate limiting and constant-time API response normalization ensure that malicious internal workloads cannot infer secret key bits through timing analysis of API roundtrips.
- SPIFFE/SPIRE Integration: Automatically verifying cryptographic workload identities before granting key access.
- Ephemeral Session Keys: Enforcing hardware-derived ephemeral encryption keys that rotate every 60 seconds.
- Rate-Limiting & Anti-Abuse: Hardware token bucket algorithms preventing cryptographic denial-of-service (DoS) attacks.
- Immutable Telemetry: Exporting OpenTelemetry audit spans with cryptographic signatures verifying request authenticity.
