Server authentication for blocking unapproved WOW access

초록

An interesting function named Wake on WLAN (WOW) has recently captured researchers attention as one of the remote computer administration functions that may turn on the remote computerized system through the network connection at the time point of receiving a specially coded packet. The phenomenon comes from the physiognomies of the coded packet such that each and every computerized system including smart-phones in the same network area receives the code where the transaction code will be broadcasted. Just in case predetermined a piece of coded packets from a server is acquired, not only authorized users but also unapproved user within the area network can wake the computerized system up. Therefore, there are pros and cons for the WOW functionalities: The one is that once the computerized system is awake, it is vulnerable for the unapproved WOW attacks or hackings so that the possibility of information leakage can be increased. The other is a good thing such that only the activated servers among the set of servers like server-farm can be woke up, so that by reducing the electricity power Green energy possibility can be achieved. In this research, a novel technique to block Unapproved WOW attacks resulting from involuntary switch-on of a computerized system has been exploited, so that the good points can be achieved by getting controllability for the weak points.
