Is it enough to secure Just the Device? – Answer is “No”
Is not it important to secure the Data on the Device? – Answer is “It is extremely important”.

Therefore, Organizations must also secure the data as it resides on the devices and as it is transmitted over the network. Cryptography involves using algorithms to protect data.

In this section & subsequent blogs We shall discusses cryptography concepts, cryptography history, goals of cryptography, cryptosystem features, cryptographic mathematics, and cryptographic life cycle.

Cryptographic Concepts

A security professional should understand many terms and concepts related to cryptography.

Cryptographic Mathematics

All cryptographic algorithms involve the use of mathematics. The fundamental mathematical concepts for cryptography are discussed in the below mindmap
