In certain applications, it is important for a remote server to securely determine whether or not two mobile devices are in close physical proximity. In particular, in the context of an NFC transaction, the bank server can validate the transaction if both the NFC phone and reader are precisely at the same location thereby preventing a form of a devastating relay attack against such systems. In ...

Various types of φA-spaces (X,D; {φA}A∈〈D〉) are simply G-convex spaces. Various types of generalized KKM maps on φA-spaces are simply KKM maps on G-convex spaces. Therefore, our G-convex space theory can be applied to various types of φAspaces. As such examples, we obtain KKM type theorems and a very general fixed point theorem on φA-spaces. RESUMEN Varios tipos de φA-espacios (X,D; {φA}A∈〈D〉) ...

“Pairing” is referred to as the operation of achieving authenticated key agreement between two human-operated devices over a shortor medium-range wireless communication channel (such as Bluetooth, WiFi). The devices are ad hoc in nature, i.e., they can neither be assumed to have a prior context (such as pre-shared secrets) with each other nor do they share a common trusted onor off-line authori...

Wireless networks are increasingly pervasive in many commercial and business environments. Additionally, many portable computing devices now have built-in wireless networking support. With these trends we are entering a new era of mobile computing and entertainment. In this demonstration we introduce an application named MStream for mobile handheld devices such as PDAs. MStream provides customi...

Intersemiotic translation, which can happen in the process of the translation of drama for theatre, can turn more complicated when the verbal sign system of drama has already undergone interlingual translation. The purpose of this study is to find the intersemiotic changes of translation from page to stage and to show the changes of indexical, iconic, and symbolic signs in the process of inters...
