This is a lengthy and highly technical course that covers symmetric key encryption, computational security and message authent among other core principles.

2. Cryptography: Pseudo-random Generators and Block Ciphers

While this course focuses on block ciphers and pseudo-random generators, it also explains CCA or Chosen Cybertext Attack security so you can design a CCA secure scheme.

3. Diploma in Cyber Security

This is a very popular course as cryptography plays a vital role in cyber security including in email security, VPNs and data encryption.

Cryptographers are specialists in making and breaking codes and messages. They either make them secure so that only the intended recipient can read them, or they decipher them (for example, in times of war to see an enemy’s intentions).
