This paper introduces a framework called an efficient dynamic key management scheme for wireless sensor networks. It reduces the number of transmissions needed for rekeying to avoid the stale keys. In addition to energy savings, it also provides a secure communication frame work where the sensed data is encoded using RC4 encryption mechanism. The key to RC4(More)
Data has an important role in all aspects of human life and so analyzing this data for discovering proper knowledge is important. Data mining refers to find useful information (extracting patterns or knowledge) from large amount of data.
