A cryptographer is responsible for creating systems that have the ability to encrypt sensitive and private information. They write the encryption code needed for data security and use exceptionally complex and advanced encryption algorithms that keep cybercriminals at bay.

Cryptography in Cybersecurity and Network Security<\/h2>\n\n\n\n

Cryptographers in IT security<\/strong> are professionals who deal with methods for encrypting signals, data and messages <\/strong>in information processing, cyber and network security systems. They make use of these complex cryptographic methods to encrypt them.<\/p>\n\n\n\n

What does cryptography mean? <\/strong><\/p>\n\n\n\n

Cryptography refers to secure information and communication methods<\/strong> that allow only the sender and recipient to view the contents of a message. <\/p>\n\n\n\n

\"Role
Role Overview – Cryptographer<\/figcaption><\/figure>\n\n\n\n

The aim here is to make the areas of secrecy, authenticity, integrity and reliability as comprehensive as possible. <\/strong>It is thus the role of a cryptographer to ensure transmission security, integrity and reliability to prevent counterfeiting.<\/p>\n\n\n\n

In cryptography, cryptographers choose and implement an appropriate cryptosystem (aka cryptographic systems).<\/strong> This makes active and passive attack options as difficult as possible or extremely complex. <\/p>\n\n\n\n

They test systems using cryptanalysis<\/strong> – a method used to crack developed algorithms and protocols – and carry out tests from the point of view of possible attackers.<\/p>\n\n\n\n

In this article, we will focus on the role of the cryptographer<\/strong> and the use of cryptography in computer security.<\/strong><\/p>\n\n\n\n

The difference between Cryptography and Cryptanalysis<\/h3>\n\n\n\n

Cryptography = Defence<\/strong>

Cryptography is a branch of mathematics that aims to encrypt and decrypt information in order to protect it. It is used to protect the information in two states: in transit and at rest. This means that sensitive data can be protected when it is in storage (e.g. when it is in a repository) or in transit (e.g. in a bank transaction).

To encrypt information, cryptographers develop cryptographic systems or cryptosystems. These systems process the information to ‘mask’ it, using algorithms that convert it into unreadable code.

A well-known example that applies cryptography is WhatsApp, which encrypts messages exchanged by users.

Cryptanalysis = Offense <\/strong>

Cryptanalysis analyses encrypted messages to discover weaknesses, and problems and even decrypt the protected information without knowing the key or how the encryption works. <\/p>\n\n\n\n

Responsibilities<\/h2>\n\n\n\n

A cryptographer is in charge of identifying any weaknesses in cryptography, cyber, and network security systems<\/strong>. Though the duties of a cryptographer may vary according to the organisation they work for, they are mainly responsible for preventing data from being intercepted or modified (in any way) by unauthorised users<\/strong>.<\/p>\n\n\n\n

They ensure the confidentiality, integrity and authentication of the company’s information<\/strong>. To achieve this, he designs and develops the organisation’s cryptosystems<\/strong>.<\/p>\n\n\n\n

To do so, the cryptographer uses HSM (Hardware Security Module)<\/strong> devices, a hardware-based solution for managing the lifecycle of keys. Thanks to HSMs, the keys of cryptosystems are protected and the company’s information is protected.<\/p>\n\n\n\n

\"Responsibilities
Responsibilities Of A Cryptographer<\/figcaption><\/figure>\n\n\n\n

Cryptographers test cryptography theories and techniques in practice<\/strong> according to the needs of the organisation they work for. They also design robust data security systems that are near impossible to hack.<\/p>\n\n\n\n

These IT professionals are also tasked with breaking down ciphers to gain access to encrypted information.<\/p>\n\n\n\n

They create and maintain an organisation\u2019s encryption technology<\/strong> and assist cryptanalysts in going over any security gaps. Lastly, these professionals develop prototype solutions<\/strong> for a company and train staff to handle sensitive information.<\/p>\n\n\n\n
