Frequently Asked Questions on Cryptography and Cryptology
Explain types of Cryptography?
There are two typs of cryptography:
How is Cryptology used?
Individuals and organizations use cryptology to protect their privacy and keep their conversations and data secure. Cryptology maintains data confidentiality by encrypting data using an algorithm with a key known only by the sender and receiver.
What is the formula for Cryptography?
Caesar Cypher is one of the simplest cryptographic algorithms. This approach requires two inputs a number and plaintext. The time and space complexity are both O(N). The encryption formula is En(x) = (x + n) mod 26, the decryption formula is Dn(x) = (x – n) mod 26.
Give some functions of Cryptography.
- Confidentiality
- Authentication
- Integrity
- Non-repudiation
Difference between Cryptography and Cryptology
Cryptography is defined as the study of rules and regulations that protect data from unauthorized access and it is also the study of conversion of plain text to cipher text. On the other hand, Cryptology is the study of the conversion of plain text to ciphertext and vice versa. It is also called the study of encryption and decryption. One major difference between both is that Cryptology is the superset of Cryptography.
