What is Digital Asset Security?
Digital asset security protects the private keys that control ownership and transaction authority for cryptocurrencies, stablecoins, tokenized securities and deposits, and real-world assets. As adoption grows across financial services, Luna HSMs help protect those keys inside certified hardware, reducing the risk of financial loss, operational disruption, and reputational damage.
Digital Asset Security Backed by Luna HSMs
Thales Luna HSMs provide a certified hardware root of trust for digital asset platforms by securing private keys and signing operations inside tamper-resistant hardware. Available in multiple form factors, on-premises or as a service, they help keep keys isolated from application layers, online systems, and cloud environments while supporting control, governance, and regulatory alignment.
Why HSMs Matter in Digital Asset Security
Luna HSMs provide the certified hardware root of trust needed to protect private keys and enforce signing controls.
Protect Private Keys
Private keys control ownership and transaction authority over digital value. Luna HSMs generate, store, and use keys inside customer-owned, FIPS-validated and Common Criteria certified hardware, keeping them isolated from applications, networks, host systems, and cloud environments.
Secure Digital Signing
Luna HSMs perform signing operations within tamper-resistant hardware to support high-value digital asset workflows. Built for crypto agility, they support NIST-standardized post-quantum cryptography algorithms and future-ready schemes for post-quantum migration.
Enforce Governance
Granular controls enforce multi-approval signing, address whitelisting, and transaction limits. Separation of duties and immutable audit logs strengthen governance, transparency, and operational control, and auditability, across digital asset environments.
Support Compliance
Luna HSMs support alignment with global frameworks including SFC, MAS, MiCA, BaFin, and FINMA. Hardware-enforced protection, key segregation, and auditability help meet evolving regulatory expectations.
Support Custody Models
Luna HSMs support hot, warm, and cold signing workflows, enabling real-time approvals or fully offline operations. This flexibility helps institutions align key protection with different risk models and custody approaches.
Connect Ecosystems
Luna HSMs integrate with custody platforms, blockchain infrastructure, tokenization engines, and APIs. They connect to on-ramps, off-ramps, and settlement systems while keeping private keys fully protected in hardware.
How Luna HSM fits into digital asset architectures
Luna HSMs secure the cryptographic operations behind digital asset workflows such as stablecoins, cryptocurrencies, security tokens, tokenized real-world assets, and CBDCs by protecting private keys and signing operations inside certified hardware.
Luna HSMs integrate with leading technology partners, custody platforms, blockchain infrastructure, and open source ecosystems, helping institutions extend hardware-based key protection without redesigning broader architectures.
Thales Luna HSM Universal Client supports broad API compatibility, including PKCS#11, Java, OpenSSL, and Microsoft CAPI/CNG, helping digital asset platforms connect through familiar interfaces while maintaining hardware-based control.
Luna HSMs can be deployed on-premises, through the Luna Cloud HSM DPoD Marketplace, or in dedicated cloud environments, giving institutions flexibility across custody, infrastructure, and operating models.

Frequently asked questions
Digital assets are forms of value represented and transacted in digital form, including cryptocurrencies, stablecoins, tokenized securities, tokenized deposits, and real-world assets. Because private keys determine ownership and transaction authority, protecting those keys with HSMs is essential as digital assets move deeper into modern finance.
Private keys control ownership and transaction authority in digital asset environments. If a key is lost, stolen, or misused, the result can be immediate financial loss, operational disruption, and loss of trust. That is why HSMs play a central role in digital asset security by protecting keys inside certified hardware.
HSMs help protect private keys by generating, storing, and using them inside certified tamper-resistant hardware rather than exposing them to software or host environments. As digital asset operations scale, software-only key protection is often not enough to support stronger signing control, governance, and auditability.
Luna HSMs provide a certified hardware root of trust for digital asset environments, supporting key generation, access control, and transaction signing across hot, warm, and cold workflows. They help organizations secure high-value operations with stronger control over keys, signing, and policy enforcement.
Luna HSMs sit at the trust layer of digital asset environments, securing the cryptographic keys used across custody platforms, wallet technologies, tokenization systems, and blockchain-based workflows. They integrate with broader digital asset ecosystems while providing hardware-based protection for critical cryptographic operations.
Yes. Luna HSMs are available in multiple form factors, on-premises or as a service, allowing organizations to align hardware-based key protection with security, operational, and infrastructure requirements across different digital asset environments.
Luna HSMs help organizations strengthen governance through hardware-enforced controls, separation of duties, policy-based access, and audit logging. These capabilities help support alignment with evolving regulatory and operational expectations in digital asset markets.
