Multi-Party Computation (MPC) Key Management & Post-Quantum Cryptography
Swiss private banking cryptographic enclave securing sovereign data vaults with Multi-Party Computation, zero-knowledge attestation, and hardware security module orchestration across multi-cloud infrastructure.
Zero plain-text key exposure in memory or at rest
Sub-millisecond mathematical shard derivation
Hardware Security Module (HSM) cluster attestation
Swiss Federal Data Protection Act & GDPR Art. 32
Swiss private wealth managers and international banking groups faced severe regulatory barriers when transitioning customer records and transaction vaults to the public cloud. Under FINMA circulars and the Swiss Federal Act on Data Protection (FADP), banks are legally prohibited from granting third-party hypervisors or foreign cloud providers access to decryption keys.
Traditional Hardware Security Modules (HSMs) created rigid operational silos and required weeks of manual ceremonies for key rotation. If a cloud provider was subpoenaed under the US CLOUD Act, traditional encryption provided zero legal defense because the cloud host held master encryption keys in memory.
Core Workstreams Executed:
- Engineered a Multi-Party Computation (MPC) key management architecture using Shamir's threshold secret sharing protocols.
- Deployed isolated AWS Nitro Enclaves and Thales Luna HSM clusters to guarantee zero plain-text key storage.
- Integrated post-quantum cryptographic primitives (ML-KEM / ML-DSA) to future-proof banking assets against quantum cryptanalysis.
- Established continuous remote attestation protocols and deterministic tamper-proof audit nonces for FINMA regulatory inspections.
Cryptographic Enclave Health & Key Governance Telemetry
The sovereign security control center provides real-time cryptographic telemetry. Security officers can monitor active MPC key shards, hardware tamper sensors, and enclave attestation status across global data centers.
- check_circle Continuous verification of 2.8M active cryptographic keys across independent jurisdictions
- check_circle Real-time hardware tamper detection with instant cryptographic key self-destruction circuits
- check_circle Sub-10ms cryptographic operation speeds handling over 14,000 signature requests per second
Multi-Cloud Attestation Status & Audit Nonce Ledger
A microscopic view into the enclave attestation verification engine. Every cryptographic request must pass remote cryptographic hardware attestation before key shares participate in computation.
- check_circle Real-time validation of cryptographic measurement hashes (PCR registers) on AMD SEV and AWS Nitro
- check_circle Automated zero-downtime key rotation executed every 24 hours without service disruption
- check_circle Cryptographic proof-of-custody nonces exported directly for external FINMA and SOC-2 auditors
Our cryptography engineers deployed an MPC threshold scheme where the private key is never assembled in a single location. Instead, mathematical key shares are distributed across three distinct legal jurisdictions: on-premises bank HSMs, a Swiss sovereign cloud enclave, and the client's public cloud tenant.
When a decryption or signature operation is requested, cryptographic co-processors perform a secure multi-party computation protocol. The message is decrypted or signed without ever reconstructing the private key in plaintext memory, mathematically neutralizing cloud host compromises.
