What is the author's purpose in writing this paragraph?
Although traffic analysis, tempest attacks, viruses and
Trojan horses are all useful techniques for gathering
information, cryptanalysts realize that their real goal is to
find a way of cracking the RSA cipher, the cornerstone of
modern encryption. The RSA cipher is used to protect the
most important military, diplomatic, commercial and
criminal communications - exactly the messages that
intelligence gathering organizations want to decipher. If
they are to challenge strong RSA encryption,
cryptanalysts will need to make a major theoretical or
technological breakthrough.
