Thales, a leader in critical information systems, cybersecurity and data security, announces integration of its market-leading nShield hardware security module (HSM) with Chain, provider of enterprise-grade blockchain infrastructure that enables organizations – including Nasdaq, Citi and Visa – to build breakthrough financial products and services.

Blockchain is driving transformation for businesses across multiple sectors, particularly financial services. The shared ledger model offers the financial industry a new model for transacting between organizations that is more efficient and secure than legacy systems. Cost savings, faster transactions, and improved data quality add to the many benefits of the technology. Underpinning each blockchain is robust cryptography used to protect the data from fraud perpetrated by hackers.

Security of a blockchain depends upon the security of its cryptographic keys. Every transaction executed through a blockchain process requires a new set of one-time keys. Chain uses the Thales nShield HSM to generate and secure these critical keys. With unique customer needs in mind, Chain developed the Chain Key Derivation algorithm using ThalesCodeSafe technology. This provides the unique capability to move sensitive applications within the protected perimeter of the FIPS 140-2 level 3 nShield HSM. Additionally, the solution incorporates robust cryptographic techniques, which securely and efficiently generate temporary one-time keys for each transaction.

Ryan Smith, Chief Technology Officer at Chain, says:

“As Chain takes blockchain networks to production, we’ve invested heavily in the secure generation and storage of private key material. The Thales nShield HSM offers a fast and efficient way to derive new keys. In particular, we were very impressed with the HSM’s CodeSafe feature, which allows us to run security-critical code protected within the HSM boundary. It’s a natural fit.”

Jon Geater, Chief Technology Officer at Thales e-Security, says:

“Blockchain is a game-changer in the financial services industry, with the potential to enhance security, speed and operational efficiency. Our integration with Chain provides a strong root of trust and ensures the integrity of the underlying blockchain operations that enables allows organizations to build, deploy, and operate blockchain-based transaction networks with confidence.”
