A wireless sensor network (WSN) consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure. and to cooperatively pass their data through the network to a main location. The process of uploading new code or changing the functionality of existing code is called Wireless reprogramming. For security reasons, every code ...

Advances in communication technology have seen strong interest in digital data transmission. However, illegal data access has become more easy and prevalent in wireless and general communication networks. In order to protect the valuable data from illegal access, different kinds of cryptographic systems have been proposed. In this paper, a new integrating channel coding and cryptography design ...

A linear error-block code is a natural generalization of the classical error-correcting code and has applications in experimental design, high-dimensional numerical integration and cryptography. This article formulates the concept of a linear error-block code and derives basic results for this kind of code by direct analogy to the classical case. Some problems for further research are raised. ©...

Traditional identification-centric RFID system (IRS) is designed to provide services of object identification/tracing/locating, but it has some shortcomings when encountering a dynamic environment in which the status of the systems and the service requirements of users/objects may change continuously. Very recently a new Code-centric RFID system (CRS), which is far different from the traditiona...
