 Secure Socket Layer (SSL)
The security communication protocol encrypts data to prevent security threats.
 Internet Printing Protocol (IPP)
IPP is a standard printing protocol used for managing and administering print jobs. It can be used both
locally and globally so anyone in the world can print to the same machine.
 IPPS
The version of the printing protocol Internet Printing Protocol (IPP Version 1.0) that uses SSL.

 CA (Certificate Authority)
A CA is an entity that issues digital certificates (especially X.509 certificates) and vouches for the binding
between the data items in a certificate.
 CSR (Certificate Signing Request)
A CSR is a message sent from an applicant to a CA in order to apply for issue of a certificate. The CSR

to verify that a public key belongs to an individual. The format is defined by the x.509 standard.
 Public key cryptosystem
A Public key cryptosystem is a modern branch of cryptography in which the algorithms employ a pair of
keys (a public key and a private key) and use a different component of the pair for different steps of the
algorithm.
 Shared key cryptosystem
A Shared key cryptosystem is a branch of cryptography involving algorithms that use the same key for two
different steps of the algorithm (such as encryption and decryption).
