Cryptographic Protocols Berry Schoenmakers, TU Eindhoven 2023 The field of cryptology is generally divided into the two mutually dependent fields of cryptography and cryptanalysis. Cryptography concerns the design of (mathematical) schemes related to information security which resist cryptanalysis, whereas cryptanalysis is the study of (mathematical) techniques for attacking cryptographic schemes. The following distinction is commonly made between cryptographic algorithms, cryptographic ...
