Components of cryptography
Data encryption translates data into another form, or code, so that only people with access to a secret key (formally called a decryption key) or password can read it.
Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext..

How does cryptography play a role in modern day communication system?
It ensures the integrity of your data
If a system possesses integrity, it means that the data in the system is moved and processed in predictable ways.
Even when the data is processed, it doesn't change.
Cryptography ensures the integrity of data using hashing algorithms and message digests..
How does encrypted communication work?
How encryption works.
Encryption works by encoding “plaintext” into “ciphertext,” typically through the use of cryptographic mathematical models known as algorithms.
To decode the data back to plaintext requires the use of a decryption key, a string of numbers or a password also created by an algorithm..
What is a cryptographic system?
The term cryptosystem is shorthand for "cryptographic system" and refers to a computer system that employs cryptography, a method of protecting information and communications with codes so only those for whom the information is intended can read and process it..
What is cipher communication?
cipher, any method of transforming a message to conceal its meaning.
The term is also used synonymously with ciphertext or cryptogram in reference to the encrypted form of the message.
A brief treatment of ciphers follows..
What is communication encryption?
Encrypted communications is when two entities are communicating and do not want a third party to intercept or to listen in.
Encrypted communication means people can share information with varying degrees of certainty that third parties cannot intercept what was said..
What is cryptographic communication?
Cryptography is the process of hiding or coding information so that only the person a message was intended for can read it.
The art of cryptography has been used to code messages for thousands of years and continues to be used in bank cards, computer passwords, and ecommerce..
- Data Confidentiality, Data Integrity, Authentication and Non-repudiation are core principles of modern-day cryptography.
Confidentiality refers to certain rules and guidelines usually executed under confidentiality agreements which ensure that the information is restricted to certain people or places.
