Enigma Machine and Cryptography

As well as being a mathematician, Alan Turing is famous for being a:

• Cryptographer

• Librarian

• Philanthropist

• Stamp collector

Answer explanation

A cryptographer analyses and decrypts information contained within cipher texts and encrypted data.

Cipher text is…

• the result of encryption performed on plaintext

• a group conversation between several people

• the result of decryption performed on plaintext

• a conversation between two people

Cryptography is a security measure that...

• allows untrusted or unintended middlepersons to view information

• allows the copying of information that is sent between two people

• does not allow untrusted or unintended middlepersons to view information

• deletes information that is sent between two people
