Question

What is criptography?
What are it’s benefits?
What are it’s advantages and disadvantages?

Answer 1

Answer:

1. Cryptography is associated with the process of converting ordinary plain text into unintelligible text and vice-versa. It is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it.
2. Protecting Authentication and Data across Devices
4. Cryptography helps to protect and store information across all types of mobile devices, whenever transferred. Apart from all this, it also enables security procedures such as advanced authentication that helps to deter unauthorized customers.
5. Cryptography – Drawbacks
7. A strongly encrypted, authentic, and digitally signed information can be difficult to access even for a legitimate user at a crucial time of decision-making. The network or the computer system can be attacked and rendered non-functional by an intruder.

Answer 2

Cryptology is science concerned with data communication and storage in secure and usually secret form. It encompasses both cryptography and cryptanalysis. Cryptography (from the Greek kryptós and gráphein, “to write”) was originally the study of the principles and techniques by which information could be concealed in ciphers and later revealed by legitimate users employing the secret key. It now encompasses the whole area of key-controlled transformations of information into forms that are either impossible or computationally infeasible for unauthorized persons to duplicate or undo
