Encryption algorithms, digital signatures and a private key are just a few of the safeguards cryptographers use to protect sensitive data in databases, online and in other digital environments. If you’re interested in becoming a cryptographer, you might wonder how to go about preparing for this new career path. Becoming a cryptographer requires a formal college education, as well as years of experience in a related field. Advanced degrees are fairly common in this career field, especially among industry leaders in cryptography.
What Is Cryptography?
Officially, cryptography refers to the field concerned with keeping communications private and secure through the use of codes. Low-tech, traditional methods of cryptography involve codes in which the letters in a message have been encrypted, or replaced with other letters, numbers or symbols. Decoding an encrypted message requires the use of a table or grid that shows what symbol translates to the real letter to be read. You can think of a cryptographer as both a message decoder and an expert in coding messages to keep sensitive data secure.
In the digital age, cryptography usually goes hand in hand with computer science and information technology . Cryptographers use coding, or computer programming, to keep computer networks and the digital data stored within them safe from cyber attackers. Encryption algorithms are used to encrypt data that includes sensitive information like financial data, military data and other information pertaining to national security and similarly important matters.
Despite its close relationship with computer science, cryptography is based on the theories, principles and concepts of mathematics . In fact, the United States Bureau of Labor Statistics ( BLS ) categorizes cryptographer, cryptologist, cryptanalyst and cryptographic vulnerability analyst as mathematician careers rather than computer and information technology careers. As such, math skills are, understandably, critical to career paths in cryptography. Analytical skills are also critical if you plan to make cryptography your new career.
Technical skills are important, but cryptographers also need soft skills like strong critical-thinking and problem-solving capabilities, good judgment and integrity. Another type of soft skills that are important when you become a cryptographer are communication skills. Good cryptographers develop the ability to explain technical concepts to non-technical professionals, some of whom may not even have a basic understanding of how computer cybersecurity systems work.
Additionally, having some knowledge of a foreign language may also be valuable for cryptographers, since the data being decoded may appear in the form of foreign communication signals.
Professional work experience is another common requirement for becoming a cryptographer. Many jobs in cryptography require quite a few years of experience working in the field of information security solutions or in other information technology occupations.
Coursework in a Cryptography CCG电子竞技现场直播 Program
To become a cryptographer, you’re going to need a college education in a technical course of study. Non-technical degrees don’t have the math- and computer-heavy curriculum needed to prepare students for a new career in cryptography.
In any degree program that pertains to the study of cryptography, students should strive to develop a basic understanding of each of the disciplines that make up this field: computer science, mathematical sciences and information security. Together, these disciplines teach students the skills needed to encrypt data by creating complex computerized codes and decode the messages embedded in these codes.
In particular, students should learn the methods of both symmetric encryption, which uses a single key or secret to decode the secure data, and asymmetric encryption, which uses a pair of keys. Students pursuing any sort of cryptography degree must learn data structures and mathematical algorithms, or formulas, such as cryptographic hash functions. To determine the origin of a message and verify that it came from the source it was supposed to have come from, cryptographers use short pieces of information such as message authentication codes and digital signatures.
Technical topics of study, like data structures and algorithms, are a big part of the study of computer science. The curriculum of a degree in computer science encompasses technical computer skills, like the use of programming languages in coding, and the mathematical foundations of computation.
Some students come to the field from a background in computer engineering, a field of electrical and electronic engineering. Computer engineering encompasses both hardware and software design and development.
Math skills are critical for the study of cryptography, so you should be prepared to take math classes if you want to become a cryptographer. Aspiring cryptographers should take courses in discrete mathematics, linear algebra, matrix algebra, probability and statistics, number theory, group theory and finite field theory.
Keeping data secure is the key purpose of the field of information security. Data encryption is just one of the possible security solutions at the disposal of cybersecurity professionals. The field of information security encompasses everything from cyber law and policy to malware analysis, digital forensics and the principles of ethical hacking.
Other Programs of Study for Work in Cryptography
Students don’t always come to the field of cryptography with a degree in this specific area of focus. In fact, programs of study devoted strictly to cryptography can be difficult to find, especially at undergraduate levels. Instead, students may major in any of the programs of study related to this field as they begin working to become a cryptographer.
Students from a math-focused background often start out with a bachelor’s degree in mathematics, applied mathematics or applied mathematical sciences. A major like data science or data analysis is another math-heavy option that may prepare students for a cryptographer career path.
For students who are more interested in the computer technology aspect of the field of modern cryptography, a degree in computer science may be ideal. Through this degree, students can gain knowledge of the mathematical models and principles from which computer algorithms arise, as well as develop their familiarity with the use of various computer programming languages. If it’s the security aspect of cryptography that you find most interesting, you might instead opt to major in information security or cybersecurity.
Ultimately, the name of the program of study that appears on your degree matters less than the competence and technical skills you cultivate as you pursue your degree. Aspiring cryptographers are encouraged to strategically use their elective to build a base of knowledge in each of the areas that contribute to the interdisciplinary field of cryptography and to apply for internships through which they can gain real-world experience in data encryption.
