C
Certificate Authority, Certification Authority. A third-party entity that is responsible for issuing and
CA
revoking certificates. Each device with the public key of the CA can authenticate a device that has a
certificate issued by the CA. The term CA also refers to software that provides CA services. See also
certificate, CRL,
A temporary repository of information accumulated from previous task executions that can be reused,

decreasing the time required to perform the tasks. Caching stores frequently reused objects in the system
cache, which reduces the need to perform repeated rewriting and compressing of content.
Cipher Block Chaining. A cryptographic technique that increases the encryption strength of an
CBC
algorithm. CBC requires an initialization vector (IV) to start encryption. The IV is explicitly given in

CHAP
Common Internet File System. It is a platform-independent file sharing system that provides users with
CIFS
network access to files, printers, and other machine resources. Microsoft implemented CIFS for
networks of Windows computers, however, open source implementations of CIFS provide file access
to servers running other operating systems, such as Linux, UNIX, and Mac OS X.
