What is master key in AES?

What is master key in encryption?

Master keys, which are stored in secure hardware in the cryptographic feature, are used to encrypt all other keys on the system. All other keys that are encrypted under these master keys are stored outside the protected area of the cryptographic feature.

Why do we need master key?

A master key system allows two or more keys to open one lock and provides different levels of access at each stage of the system's hierarchy. This provides extra levels of security to your premises by enabling you to control who can access which areas without the hassle of large amounts of individual keys.

What is a zone master key?

A Zone Master Key (ZMK) is a key-encrypting key which is distributed manually between two (or more) communicating sites, within a shared network, in order that further keys can be exchanged automatically (without the need for manual intervention).

What key is used in AES encryption?

Data Encryption Encryption works by taking plain text and converting it into cipher text, which is made up of seemingly random characters. Only those who have the special key can decrypt it. AES uses symmetric key encryption, which involves the use of only one secret key to cipher and decipher information.
