Computer security is an important field of study for most day-to-day transactions.It arises
when we turn on our cellular phones,check our voice mail and e-mail,use debit or credit
cards,order a pay-per view movie,use a transponder through EZ-Pass,sign on to online
video games,and even during visits to the doctor.It is also often used to establish virtual private networks (VPNs) and Secure Shell connections (SSH),which allows employees to
telecommute and access computers remotely.
The use,and often misuse,of cryptography to solve security problems are driven by one
cause:the need for security.Simply needing security does not make it so,a lesson all too often
learned after the fact,or more importantly,after the exploits.
The Mythic exploit is a classic example of not knowing how to use tools properly.It is
hard to fault the developer team.They are,after all,video game developers,not fulltime
cryptographers.They do not have the resources to bring a cryptographer on team,let alone
contract out to independent firms to provide the same services.
The circumstances Mythic was in at the time are very common for most software development companies throughout the world.As more and more small businesses are created,the
fewer resources they have to pool on security staff.Security is not the goal of the end-user
product,but merely a requirement for the product to be useful.
For example,banking hardly requires cryptography to function; you can easily hand
someone $10 without first performing an RSA key exchange.Similarly,cell phones do not
require cryptography to function.The concept of digitizing speech,compressing it,encoding
the bits for transmission over a radio and the reverse process are done all the time without
one thought toward cryptography.
