What exactly is cryptography? How can one deploy it? For what purposes is it used? How can it be used to secure the confidential information and data of an organization? How can cryptography be used to secure the lines of network communications between a remote worker and the corporate servers?
These are all questions that a well-trained cryptographer can answer. They are well-versed in all aspects of this amazing part of cybersecurity, with everything from its deployment to how it can best be used to meet the security requirements of any organization.
In this article, we will examine the top thirty questions that can be asked of an experienced cryptographer, ranging from what it is all about to its commercial applications. These types of questions can be broken into down into Level 1, Level 2 and Level 3 Questions. These questions can also be used in an interview situation when a business or a corporation wishes to hire a cryptographer, either on a full-time or contract basis.
Level 1 Questions
1. What is cryptography?
Cryptography is a specialized area of cybersecurity, but it has a broad array of applications that we will examine later. Kaspersky Lab has defined it as follows: “Cryptography is the study of secure communications techniques that allow only the sender and intended recipient of a message to view its contents. In addition, cryptography also covers the obfuscation of information in images using techniques such as microdots or merging.”
2. What exactly are encryption and decryption?
The terms “scrambling” and “descrambling” are commonly known. In terms of decryption, scrambling and descrambling are also known as “encryption” and “decryption.”
For example: when the written message “I LOVE YOU” is scrambled by the sending party, it becomes what is known as the “encrypted message.” This (Read more...)
