Codebusters Test Assessment Design 2

Question 1

In a Codebusters assessment, what is the primary purpose of including an Aristocrat cipher?

Accepted Answer

To test monoalphabetic substitution decoding with word divisions preserved

Answer

To test polyalphabetic cipher skills

Answer

To assess knowledge of transposition techniques

Answer

To evaluate RSA public-key decryption

Question 2

How does a Patristocrat cipher differ from an Aristocrat cipher in terms of assessment design?
