Overview 14

In today’s world there are many security threats to your network and the data that travels over it. Your Brother

machine employs some of the latest network security and encryption protocols available today. These

network features can be integrated into your overall network security plan to help protect your data and

prevent unauthorized access to the machine. This chapter explains various security protocols supported and

how to configure them.

Security terms 14

 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

contains information identifying the applicant, the public key generated by the applicant and the digital

signature of the applicant.

 Certificate

A Certificate is the information that binds together a public key with an identity. The certificate can be used

to verify that a public key belongs to an individual. The format is defined by the x.509 standard.

 Digital signature

A Digital signature is a value computed with a cryptographic algorithm and appended to a data object in

such a way that any recipient of the data can use the signature to verify the data's origin and integrity.

 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).
