Cryptography Questions
A key derivation protocol is a cryptographic process that generates one or more secret keys from a shared secret or a master key. It is used to derive additional keys for various purposes, such as encryption, authentication, or secure communication. The protocol typically involves applying cryptographic algorithms and functions to the shared secret or master key, along with other parameters, to produce the derived keys. Key derivation protocols are essential for ensuring the security and confidentiality of data in cryptographic systems.
