Wireless network connection control method of performing control for establishing and releasing wireless network connection with another device when impacts are applied to devices, application program control method of performing control for setting and executing application program when impacts are applied to devices, and device including wireless network connection control function and application program control function which use a device impact are disclosed. According to the present invention, provided is a wireless network connection control method of a device using a device impact, including generating a corresponding impact event when physical impact applied from the outside is sensed, transceiving a search message between devices based on a time at which the impact event occurred, searching for another device in which the impact event has occurred at the same time, and performing a predetermined protocol with a corresponding device according to a search result and establishing an inter-device wireless network connection.

Wireless network connection controlling method using device impact, application program controlling method, and devices thereof

A method and apparatus for generating a non-interactive key, and a method for communication security using the same. A event is detected, and keys are generated based on the detected event. Thus, keys are generated using a small number of calculating operations with a simple interface and thus a user may easily generate the keys, and the performance of an apparatus using the keys is improved. In addition, the keys are generated without wireless interaction between nodes, thereby improving communication security.
