This study proposes a three-factor control protocol for universal serial bus (USB) on an elliptic curve cryptosystem (ECC). USB is a universal interface used in an enormous number of devices. It has become the most popular interface standard for computer connections. However, since USB provides high transmission speed and is very convenient to carry, many(More)
In recent years, on the researches in various routing protocols, applications to digital home wireless heterogeneous networks become more and more important. In this paper, we propose a routing protocol based on event-oriented applied for digital home wireless heterogeneous networks, and a knowledge discovery agent will dynamically maintain an n-bits map(More)
IPTV (Internet Protocol Television) is a very important field in the network development. Comparing to the traditional television, the IPTV combines the digital contents like media. The communication and the advertisement with the interaction serve into the emerging business model to provide the users to watch television service. Because the IPTV contains(More)
Sensor nodes are resource-constrained, such as low battery life, computation, bandwidth and memory, so traditional public key schemes are impractical in wireless sensor networks. In the previous schemes, symmetric cryptography is the most common method used in sensor nodes. How to distribute keys into every sensor node is an important issue in many(More)
The main purpose of this study was to establish an industry-based basic technological competence indicator system of electrical technology for students at a technological institute. To establish these standards, 12 people were interviewed, whose detailed comments were collected to establish the content for basic competence indicators in electrical(More)
