If you have outstanding mathematical skills, enjoy riddles, and can’t get enough of technology, you may be a good fit for a cryptography job in cyber security. Many organizations require secure databases, systems, and customer service. Undoubtedly, the domain is experiencing exponential growth. The government is also in need of cyber security cryptographers to secure military data from both foreign and internal adversaries.
This article is all about cryptography and how to become a lifelong cryptographer. Read this article to know how to become a cyber security cryptographer.
What is a Cyber Security Cryptographer?
A cyber security cryptographer is an information technology (IT) expert who specializes in data security using cryptosystems. That is, they gather information and render it unreadable to outside attackers. Cryptographers design security mechanisms. Because this domain is mathematically driven, a mathematical background is often needed. Cryptographers may also have a computer science background. Cryptographers mainly deal with stopping attackers from hacking their data.
Cryptographers work for companies like law enforcement or the National Security Agency. For state or municipal government. Most operate in the private sector, assisting their customers or employers in protecting their data from any security risks.
What Does a Cyber Security Cryptographer Do?
A cryptographer encrypts data and creates systems so that data can be secured, and can only be accessed by those with permissions. That is, the data is useless if nobody can access it. Depending on the need, a cryptographer sets up encrypted email or chat systems that no one can access but the users. Other cryptographers work to secure financial transactions. Cryptocurrencies such as Bitcoin are secured by a cryptosystem known as the blockchain.
Cryptographers devote a significant amount of time to research in their specialty. Because cyber security is expanding rapidly, information security experts must stay up to date on current developments. After all, black-hat hackers certainly do the same thing. Once a hacker has gained access to an encrypted system, they can view all of a company’s records, including financial information, as well as valuable intellectual property.
It’s also essential that cryptographers keep their systems up to date with new encryption algorithms and various layers of encryption. Because a system breach can occur without anyone’s forewarning and last for a long time, cyber security policies must be constantly revised.
Cyber Security Cryptographer Skills to Acquire
Number Theory:
The study of whole numbers is known as number theory. To be a good cryptographer, you must have a high degree of mathematical expertise; this field seems esoteric for many, but you must grasp how prime numbers are distributed, for example.
Linear Algebra:
To grasp vectors, matrices, and vector spaces, you must first study linear algebra. In WWII, the Germans employed linear algebra to develop the Enigma machine. Fortunately, some bright cryptographers deciphered and cracked the Enigma code, most likely by reverse-engineering the algebraic correlations they identified.
Combinatorics:
Combinatorics is the study of how many possible combinations can be created from a particular collection of things, such as letters or integers. This is important for encrypting data since it allows you to mix up all of the characters in a confidential document so that anyone who attempts to access it will be unable to operate with it. You can apply a cypher to the document and decipher it for valid purposes.
Communication:
Although cryptography is a highly analytical domain that focuses on numbers and abstract symbols rather than communication, you will be required to create briefings and even guides for the project team and stakeholders. After all, if you encode important papers for your CEO, they must be able to decrypt them if necessary. Furthermore, you need to decode a non-technical employer’s cryptography requirements to give them the security measures they require.
Steps to Become a Cryptographer
Step 1
If you’ve ever been attracted by logic puzzles, breaking codes, or even computer programming, you could be a good candidate to become a cryptographer.
You will undoubtedly require a high aptitude for math. Math is at the heart of practically every scientific or technical sector. Mathematical algorithms are essential in cryptography for scrambling text communications so that individuals who do not have the key cannot read the information. Aspiring cryptographers will find that they have a genuine desire to learn about these methods and may even begin developing their own.
Thus, the first step toward becoming a cryptographer is to explore the domain as a passion.
Step 2
Formal schooling is the second stage toward becoming a cryptographer. If you have not yet enrolled in a college degree program, you can explore the online programs that teach higher-level mathematics and cryptography.
There are online cybersecurity certification courses available. Do check out Great Learning’s cybersecurity certification program, as the program helps you to know about the fundamentals of cryptography, such as Types of cryptography, Hash functions, and Digital signatures. Public Key Infrastructure, Attacks on cryptosystems, and much more, Hands-On experience with Live Instructor-led Classes.
Step 3
To truly excel as a cryptographer, you must first have a bachelor’s degree. As the sector is quite sophisticated, it is strongly advised that you obtain the best qualifications viably. You could even think about pursuing a cyber security program at the graduate level. Look for the cyber security program that has the highest level of certification.
Step 4
Once you have a degree, you should not just look for an entry-level position in an IT or cyber security department. You should always continue broadening and enhancing your expertise. You can accomplish this by enrolling in a cyber security program with valid certifications from a reputable institute.
Look for courses that include cryptography and other areas like database administration or networking. When you obtain a certification that involves additional training, possibly involving periodic tests, your credentials will reflect that your knowledge is continuously evolving and improving. While you can always keep learning new things, having a recognized credential shows that your efforts are persistent and valuable.
Conclusion
Cryptography has been used for ages, and it does not seem that careers in cryptography will be diminishing anytime soon. If you want to be one of the cyberworld’s sheriffs, a compelling career awaits you.
Explore Great Learning’s cyber security program, instructor-led training, and Interactive Sessions. Live and self-paced classes equip you to block hackers and keep your company’s systems with hands-on demonstrations. Now accelerate your career by expanding your knowledge in the domain of cyber security cryptography at your convenience.
