Security Foundations

The strength of Secubit’s rests on its security foundations. These foundations define how cryptographic material is created, protected, and used, ensuring that every operation is trustworthy and resistant to compromise.

Rather than relying on the security of servers or networks, Secubit is built on hardware-rooted trust anchored in tamper-resistant HSMs. Within these devices, private keys are generated using True Random Number Generators, stored in secure hardware, and never leave the protected environment in plaintext. All sensitive operations—such as user authentication, transaction signing, and policy enforcement—are executed inside the HSM boundary, providing strong guarantees against insider abuse, software compromise, or external attacks.

This chapter introduces the core building blocks of Secubit’s security model: key generation, key storage, user authentication, transaction signing, policy checking, and secure software updates. Together, these mechanisms form the foundation that enables bank-grade security, self-sovereign control, and compliance with institutional standards.
