Abstract
By the rapid development of the mobile device technology, expensive contents and/or privacy information come to be communicated between the terminals of the users. Currently, as the encrypting key for secure ad-hoc communication, a fixed key or PIN code is commonly used between conventional mobile devices. However, the length of these keys is generally short and the setting of the keys is bothersome. In this paper, we propose a method to generate a common key between mobile devices based on the similarity of the users' movements measured by the accelerometers. The experimental result showed that from a pair of the movements with middle similarity a common key equivalent to the PIN code can be generated within 1 minute.
