“…When users shake devices together, the method [3] performs pairing by generating a common key necessary for encrypting transmission / reception data. This method generates a common key by combining the partial keys generated from the partial data sets of acceleration data.…”

“…Our proposed method does not need special camera such as infrared camera because of only recognizing the marker by a camera. • Can distinguish legitimate user from impersonator In [3], there is possibility that the impersonator outside the camera range can imitate the movement of the device of two users because this method generates common key from two acceleration data of two users directly. In [10,11], there is also possibility that the impersonator can perform illegal pairing by imitating the user's movement because inclination of device is not detected or calculated.…”

Currently, devices with wireless technologies often communicate each other ad hoc. For example, a presenter wirelessly distributes ad-hoc meeting materials from a PC to mobile device in a meeting room. However, there is a problem of spoofing by an impersonator outside the room. Hence, devices must conduct secure pairing, which is exchange of key necessary for encrypting communication contents, before the communication. As a pairing method between devices, there are pairing methods using RSS from access point as features. However, RSS changes significantly due to environmental factors. On the other hand, there are the pairing methods which compare acceleration data from devices with displacement data of devices from camera of a server. However, these methods have problems that it is necessary to use infrared camera and difficult to recognize inclination of devices. Thus, these methods cannot perform accurate device pairing. Therefore, in this paper, we propose a method that perform pairing using devices' accelerometers and markers displayed on devices, and a camera of authentication server. This method performs pairing by calculating similarity between velocity data from acceleration data from devices and displacement data of the marker from camera after comparing marker sequence displayed on the device. This method has advantage that can detect devices' inclination by recognizing markers' inclination. We performed three types of experiments to confirm the similarity of displacement data and acceleration data, whether an impersonator outside camera range can perform pairing, and possibility of several devices pairing together. As a result, we founded that the larger the device's display is, the higher the similarity, the proposed method can distinguish legitimate user from impersonator outside camera range by average similarity, and three devices succeeded pairing at rate of 71.8%.

A similar protocol that utilises rudimentary error correction of binary keys created by shaking processes is introduced in [1].

With the capabilities of computing increasing by leaps and bounds, the need for trusted communication also rises. The present state of ensuring secure communication between devices largely relies on the use of cryptographic keys. The primitive and advanced key generation strategies involve the use of password only, biometric, quantum, PRNG technologies. Recently, the use of contextual information to generate highly secure keys has proven to be a realistic and unobstructed method in the field of cryptography. Contextual information like temperature, luminance and ambient audio may be used for this purpose. This paper presents a detailed survey on the cryptographic techniques for key generation based on contextual information. A brief comparison on the current techniques is also presented in this survey.
