Cryptology
What is it?
Cryptography: designing algorithms to
ensure
confidentiality,
authentication, integrity, and so on
Usually based on a secret called key and/or specific mathematical
functions (one-way)
Cryptanalysis: designing algorithms to
bypass
confidentiality,
authentication, integrity, and so on
Usually based on complex mathematical theories, but also on good
tricks to achieve the same goals (operational cryptanalysis)
