The difficulty is based on having the pcs timed flawlessly to each other so the receiving laptop knows it will accept the incoming password at this time. Another type of excessive security password system is a challenge-response system. This system makes the users memorize a group of rules to convert an issue issued by computer into the correct response (Net Reliability, 2). The drawback to this technique is that when you have a large number of computer users, it is difficult to acquire everyone memorize the rules, guarantee the rules will be easy enough to not forget, and keep the principles secret.
