Key Seclusion is the cryptographic security practice of isolating and protecting private keys used for signing transactions or accessing digital assets. It ensures these keys are never exposed to unauthorized entities or vulnerable system components.
Mechanism
This practice typically involves storing keys within hardware security modules (HSMs), utilizing multi-party computation (MPC) schemes, or employing trusted execution environments (TEEs). Access to these secluded keys is strictly controlled through robust authentication and authorization mechanisms.
Methodology
Implementation relies on secure hardware, advanced cryptographic techniques, and stringent operational procedures to prevent key exfiltration or compromise. This approach is fundamental for safeguarding institutional crypto holdings and maintaining the integrity of transaction authorizations in high-value trading systems.
