Definition ∞ Key derivation is a cryptographic process used to generate new cryptographic keys from a master secret, such as a password or a seed phrase. This method allows for the creation of multiple, distinct keys from a single source of entropy, enhancing security and manageability. It is a foundational element in securing digital wallets and ensuring the privacy of user data.
Context ∞ Key derivation functions are a frequent topic in technical explanations of cryptocurrency wallet security and private key management. Current discourse often focuses on the specific algorithms used, such as BIP39 or HKDF, and their resistance to brute-force attacks. Ongoing research explores new methods for secure key generation and management that can adapt to evolving cryptographic standards and threat models.
