Abstract

Standby power consumption of electric devices is a major issue. It accounts for 5 % to 14 % of the total residential power consumption. However, applying state-of-the-art power management techniques can reduce this waste of energy drastically.

In this paper we present an innovative and secure Near Field Communication (NFC) Interface technique for everyday electronic devices. By integrating this field-powered and secure communication interface, a target device can be switched off during standby. If user interaction is requested, NFC provides the electrical energy to switch on the target device’s power supply and to start the device. Thus, standby power consumption of an NFC enhanced device is eliminated completely. Besides standby power management, our interface features cryptography, innovative hardware abstraction and user interface concepts, and it enables configuration, monitor, and control tasks of the target device.

Zusammenfassung

Der Standby-Leistungsverbrauch elektronischer Geräte markiert ein stetig wachsendes Problem. Dieser beträgt zwischen 5 % und 14 % des gesamten häuslichen Leistungsverbrauchs. Durch Implementierung und Anwendung von Power Management-Techniken ist es jedoch möglich, diese Energieverschwendung fast zur Gänze zu beseitigen.

In dieser Arbeit präsentieren wir eine auf Near Field Communication (NFC) basierende sichere Schnittstellentechnik, die in jeglichen elektronischen Geräten integrierbar ist. Dank dieser Funkschnittstelle kann ein Gerät während der Standby-Zeit komplett abgeschaltet werden. Falls ein Benutzer mit dem Gerät interagieren möchte, wird die von NFC bereitgestellte elektrische Energie verwendet, um das Gerät wieder einzuschalten. Somit kann der Standby-Leistungsverbrauch eines Gerätes unterdrückt werden. Neben Power Management, unterstützt die Schnittstelle Kryptographie, als auch innovative Hardwareabstraktions- und Userinterfacekonzepte. Ferner bietet die Schnittstelle Funktionen zur Konfiguration, Beobachtung und Steuerung eines elektronischen Gerätes an.
