Wireless sensor nodes has been used for the sensing the information from harsh environment. In these nodes sensors of different types has been used for collecting information. In MWSNs the main threat in the network is security. Various types of attacks occurred in these networks. Attack occur in WSN is clone attack which is also known as replica attack. In(More)
The RFID and Sensor system has much benefit but simultaneously has some problems such as user's privacy violation. Ubiquitous computing requirement in security that can happen in ubiquitous environment, and by suggesting the direction of security service centered on safe key distribution, certification and sensor node capture defense technology.
