In this paper, a secure and efficient authentication and authorization architecture for IoT-based healthcare is developed. Security and privacy of patients’ medical data are crucial for the acceptance and ubiquitous use of IoT in healthcare. Secure authentication and authorization of a remote healthcare professional is the main focus of this work. Due to resource constraints of medical sensors,...

This study examines what young children learn from educational CDRoms as opposed to what software producers claim they learn. Ten children in the four to five age group were invited to play with selected CDRoms purporting to teach young children a range of skills and understandings. Two CDRoms from the same genre of "work and play resources" were chosen—Leaps and Bounds, and Jump Start Advanced...

In the last decade traditional identity documents have been equipped with an embedded NFC-chip to enable wireless access to the relevant data. This applies in particular to passports, following the ICAO standard, but increasingly also to other identification documents, such as driver’s licenses. Such electronic identity (eID) documents can now be used as “mother cards” by the users to remotely ...

The background of this research is the low PKN learning outcomes class III students at SDN Tambakmas 2 Magetan, for reason improvements are carried out by conducting classroom action using PBL model assisted Pancasila intelligenta board media. This study aims to improve smart media in Magetan. a conducted subjects were totaling 10 children. was cycles. results showed that there an increase can ...

We have built and evaluated a prototype of a tool called Knight. The tool uses an electronic whiteboard a large, touch sensitive computer screen (currently a SMART Board http://www.smarttech.com). The large drawing space resembles a traditional whiteboard: Pens are used as input devices and several persons can work around it. Thus, it naturally supports collaborative work. Furthermore, the Knig...

Zusammenfassung Neue Entwicklungen in der Elektronik wie massengedruckte Einfachelektronik ermöglichen den Einsatz von Computersystemen an oder gar in Objekten, für die bisher ein solcher Einsatz nicht wirtschaftlich sinnvoll war. Dieser Beitrag untersucht die prinzipiellen Rahmenbedingungen bei der nahtlosen Integration von Smart Objects in bestehende IT-Strukturen. Probleme bei der Einbindung...

This paper discusses methods for generating RSA moduli with a predetermined portion. Predetermining a portion enables to represent RSA moduli in a compressed way, which gives rise to reduced transmissionand storage requirements. The first method described in this paper achieves the compression rate of known methods but is fully compatible with the fastest prime generation algorithms available o...

In today’s world carrying a number of plastic smart cards to establish our identity has become an integral segment of our routine lives. Identity establishment necessitates a pre stored readily available data about self and to the administrator to authenticate it with claimer’s personal information. There is a distinct requirement of a technological solution for nationwide multipurpose identity...

Smart card systems have been spreading globally not only for purchasing general goods and services, but also for fare payment of public transport. When an individual traveller is holding a public transport smart card, the precise times of his/her passing through ticket gates are recorded in the smart card system. The longitudinal smart card data of a large number of passengers have been stored ...
