Problem:

Blockchain, given its ability to generate an immutable cryptographic record, can be useful for business transactions and has the potential to carry significant economic value. This inevitably increases the risk of theft and misuse of private keys.
Organizations looking to implement a private enterprise blockchain or a hybrid blockchain face some familiar and some unique key management challenges. Software key managers are vulnerable whereas traditional HSMs do not address the requirements of a Blockchain.

Solution:

Fortanix Self-Defending KMS delivers unmatched security and availability for private keys. Complete key management and policies for key usage are enforced inside Intel® SGX enclaves ensuring confidentiality and integrity of the policies. Fortanix Self-Defending KMS supports powerful yet easy to use policies for multisig, quorum approval, and strong access control. REST APIs and deployment model flexibility make it easy to integrate Fortanix Self-Defending KMS with distributed blockchain environments.
