Ppt cryptography and network security

What are cryptographic services cryptography and network security?
The five security services in cryptography are known as the CIA Triad.
It includes data confidentiality, data integrity, data authentication, data authorization(or access control), and non-repudiation.
Furthermore, its extensions are data availability and data accountability..
What are the objectives of cryptography and network security?
The Objectives of Cryptography
Cryptography has four major goals: confidentiality, integrity, authentication, and non-repudiation.
Put another way, the goals are data privacy (confidential treatment), data authenticity (verified source), and data integrity (original and unaltered message)..
What is cryptology in network security?
Cryptology is the science of secure communications.
Cryptography creates messages with hidden meaning; cryptanalysis is the science of breaking those encrypted messages to recover their meaning..
What is security mechanism in cryptography and network security?
Security mechanisms are technical tools and techniques that are used to implement security services.
A mechanism might operate by itself, or with others, to provide a particular service.
Examples of common security mechanisms are as follows: Cryptography.
Message digests and digital signatures..
Cryptography includes a set of techniques for scrambling or disguising data so that it is available only to someone who can restore the data to its original form.
In current computer systems, cryptography provides a strong, economical basis for keeping data secret and for verifying data integrity.
Security services provided by cryptography are also discussed such as data integrity, privacy/confidentiality, user authentication, message authentication, authorization, digital signatures, validation, access control, and non-repudiation along with their mechanisms.

9. Cryptography. The process of converting a message into a secret code called CIPHER TEXT, and changing the encoded message back to regular text called PLAIN

A network consists of two or more devices that are linked in order to share resources or allow communications. Can you think of various forms of a network? 3.
