Online Courses in Cryptography

Below are descriptions of some popular cryptography courses that are often available online.

  • Introduction to Cryptography: This course is typically designed for undergraduate students with junior or senior standing, as well as for graduate students. Cryptographic techniques are introduced through discussions on encryption, authentication, e-commerce and digital signatures. Prerequisites for the course include the theory and practice of probability.
  • Foundations of Software Security: Online students in this course usually need a bachelor's degree in computer science and a professional background in security. Training prepares them for advanced cryptography and covers topics that include principles of computer security, programming techniques, security system design and software development.
  • Internet Security and Cryptography: Students can take this course at the introductory level during a graduate program, covering topics like protocol, telecommunication security requirements, access sharing and algorithms. A capstone project may complete the program.
  • Network Security and Cryptography: This graduate-level course covers practical application and theory of cryptographic techniques and network security. Popular topics include conventional encryption, key management, electronic mail security, message authentication, firewalls and hash functions.
  • Cybercrime: Students in this class will discover methods of investigating crimes committed online, including phishing and fraud. The class will study the kinds of crimes that can be committed via the Internet, and methods of uncovering these crimes using network security and cryptography.
  • Secure Mobile Computing: In the age of mobile technology, this course explores the potential threats to mobile devices and the tools and techniques used to protect mobile data. These techniques will be tested through the use of a virtual lab environment.
  • Cloud Security: This class will cover the landscape and architectural principals of cloud computing. Topics covered may include security architecture, design patterns and industry standards.

Program Information

Online cryptography courses are primarily offered through graduate-level degree and certificate programs in specialties like computer science and software systems. They are also available for network and Internet security professionals via continuing education departments. Some online courses do exist for those new to cryptography, such as programmers or information technology (IT) specialists, who've completed a bachelor's degree in a related area. Some online classes will require purchasing a paper textbook and other supplies. Before enrolling, students will want to find out if assignments and exams are offered in a timed format or asynchronously for independent study, and whether any specialized cryptography software is required.

In modern times, cryptographers mainly focus on computing security. Students enrolled in online programs may learn about topics such as cybercrime, cloud networks and software security.
