Key Storage

Once cryptographic keys are generated, they must remain secure throughout their entire lifecycle. Secubit ensures this by relying on tamper-resistant storage within Hardware Security Modules (HSMs).

Keys never leave the secure boundary of the HSM in plaintext. Instead, they are stored internally in encrypted form, protected by device-specific master keys that are rooted in hardware. This wrapping process ensures that even if data were copied from the device, it would be useless without the HSM that created it.

The physical and logical protections of the HSM—such as intrusion detection meshes, active response sensors, and zeroization mechanisms—make unauthorized extraction nearly impossible. If tampering is detected, the device automatically erases sensitive material, preventing compromise.

Additionally, key access is governed by strict hardware-enforced policies. Roles and permissions define which operations are permitted, while quorums and dual-control workflows prevent unilateral misuse. This means that even insiders with elevated privileges cannot bypass protections to misuse stored keys.

By anchoring key storage in tamper-resistant HSMs, Secubit ensures that private keys are never exposed to host memory, operating systems, or cloud environments. This guarantees that the most sensitive assets in the system remain safeguarded against both physical and digital threats.
