Key Generation

At the heart of any secure wallet system lies the process of key generation. Cryptographic keys are the anchors of trust: if they are weak, predictable, or exposed, the entire system becomes vulnerable. For this reason, Secubit relies on True Random Number Generation (TRNG) inside its Hardware Security Modules (HSMs) to generate all cryptographic keys.

Unlike pseudo-random software generators, which rely on deterministic algorithms and can be influenced by external conditions, a TRNG uses dedicated hardware sources of entropy—such as electronic noise, oscillator drift, or quantum effects—to produce unpredictable values. These entropy sources are continuously tested to ensure health and uniformity, preventing bias or degradation over time.

By confining key generation to the HSM, private keys are created entirely within the device’s tamper-resistant boundary. They never exist in plaintext outside of secure hardware, nor do they traverse application memory, disks, or networks. This ensures that even if the surrounding infrastructure is compromised, the cryptographic root of trust remains uncompromised.

Keys generated in this way are immediately protected under the HSM’s internal master keys, and their usage is subject to strict hardware-enforced policies. Whether for signing, encryption, or participation in Multi-Party Computing (MPC), every key begins its lifecycle with strong entropy and secure creation.

This approach guarantees that the cryptographic foundation of Secubit wallets is not only mathematically secure, but also hardware-anchored and resistant to external manipulation. Key generation with TRNG inside HSMs is therefore the cornerstone of Secubit’s security model.
