key
In cryptography, a key is a variable value that is applied using an algorithm to a string or block of unencrypted text to produce encrypted text, or to decrypt encrypted text.
-
key chain
A key chain is a series of keys that can be created to help ensure secure communication between routers in a network. Authentication occurs whenever neighboring routers exchange information. Plain text authentication sends a plain text key with each message, and plain text is vulnerable to snooping. Key chains allow a rotating series of keys to be used for limited periods of time to decrease the likelihood of a compromise.
-
key fob
A key fob is a small, programmable hardware device that provides access to a physical object. Key fobs, are used to provide one-factor authentication for objects such as doors or automobiles. They are also used as an authentication factor for objects that require two-factor or multifactor authentication, such as laptops.
-
key string
A key string is the authentication code included in each key in a key chain, which is a series of keys that can be created to help ensure secure communication between routers in a network.
