The design of an RFID security protocol for saving in DB transaction costs

The low-cost RFID system will become pervasive in the ubiquitous computing environment as a common infrastructure. It presents a lot of advantages, but brings a number of open issues that need to be solved before its successful realization. One of the open issues is about the backend system loading. In this paper, we proposed an RFID security protocol that has two features, dynamic key generation function for increasing cryptographic key complexity and the efficient message protocol for the transactional load of back-end database server.
