Abstract:

Los sistemas de control de acceso se usan para permitir o denegar el ingreso de ciertas personas a un área específica en un determinado horario. Estos sistemas se usan ampliamente en hoteles, condominios y todo tipo de empresas, en los que dependiendo del usuario, se le otorga acceso a más o menos áreas. Actualmente, tienen diversas aplicaciones como control de asistencia, control de rondas y exclusas de seguridad. Los centros educativos también requieren cierto control del acceso a sus instalaciones, tanto al campus, como a áreas específicas donde personal docente o administrativo tienen acce

Abstract:

Arbetet utvärderar Ikea TRÅDFRI rörelsesensors kommunikationsprotokoll utifrån ett säkerhetsperspektiv. Internet of Things expanderar och i takt med utvecklingen är det viktigt att granska produkter på marknaden för att se hur säkerhet är implementerat. I rapporten utforskas flera olika sätt att utvärdera produkten för att få en god helhetsbild. Detta innefattar metoder kring hur en obehörig kan få tillgång till information genom avlyssning, ifall en obehörig skulle kunna ta över kommunikationen genom att parkoppla till en ljuskälla på ett långt avstånd samt en bedömning av sårbarhetsgrad utif

Abstract:

As wireless protocols become easier to implement, more products come with wireless connectivity. This latest push for wireless connectivity has left a gap in the development of the security and the reliability of some protocols. These wireless protocols can be used in the growing field of IoT where wireless sensors are used to share information throughout a network. IoT is being implemented in homes, agriculture, manufactory, and in the medical field. Disrupting a wireless device from proper communication could potentially result in production loss, security issues, and bodily harm. The 802.15

Abstract:

Wireless sensor networks (WSNs), being a relatively new technology, largely employ protocols designed for other ad hoc networks, especially mobile ad hoc networks (MANETs). However, on the basis of applications, there are many differences between WSNs and other types of ad hoc network and so WSNs would benefit from protocols which take into account their specific properties, especially in routing. Bhatti and Yue (2006) proposed an addressing scheme for multi-hop networks. It provides a systematic address structure for WSNs and allows network topology to avoid the fatal node failure problem whi

Abstract:

The increasing number of IoT devices used in today’s society has led to a demand for better security in order to prevent attackers from gaining access to private information. The IoT brings a wide application scope and because of that there are a lot of ways to set up a secure network and manage keys in these kinds of networks. This paper presents a comparison between the security model in Zigbee and the new recommended practice for Key Management Protocols defined by the IEEE 802.15.9 standard. We investigate key establishment and transportation together with the vulnerabilities that this mig

Abstract:

Monitoring and controlling smart grid assets in a timely and reliable manner is highly desired for emerging smart grid applications. Wireless Sensor Networks (WSNs) are anticipated to be widely utilized in a broad range of smart grid applications due to their numerous advantages along with their successful adoption in various critical areas including military and health care. Despite these advantages, the use of WSNs in such critical applications has brought forward a new challenge of ful lling the Quality of Service (QoS) requirements of these applications.

Abstract:

When installing new network security cameras in buildings, the cameras are often connected to sensors via signal wires. Since most building already have internet and electricity drawn throughout the structure, the procedure of routing a new signal wire can be costly and time demanding. By replacing this wire with a wireless link, the cost and time it takes for the customer to install a camera could be reduced. The objective for this thesis is to investigate different wireless technologies used in short range, low power wireless communication networks such as PANs and LANs. Focusing on technolo

Game is running without the human intervention. Just a human referee is supervising the game. Two teams are attending the game. Each of them has a control computer. The control computer is the brain of the game. It has a camera, it is making decisions for the next step of robots and sending them configuration data.
