  4. Four-square cipher - Wikipedia

    en.wikipedia.org/wiki/Four-square_cipher

    The four-square cipher is a manual symmetric encryption technique. [1] It was invented by the French cryptographer Felix Delastelle. The technique encrypts pairs of letters (digraphs), and thus falls into a category of ciphers known as polygraphic substitution ciphers. This adds significant strength to the encryption when compared with ...

  7. Problem solving - Wikipedia

    en.wikipedia.org/wiki/Problem_solving

    Problem solving is the process of achieving a goal by overcoming obstacles, a frequent part of most activities. Problems in need of solutions range from simple personal tasks (e.g. how to turn on an appliance) to complex issues in business and technical fields. The former is an example of simple problem solving (SPS) addressing one issue ...
