Now

however

traditional teaching methods fail to satisfy the particularity of the RFID system.In this paper

a key management scheme for RFID is proposed

which combines CPK (Combined Public Key) cryptography. The detailed contents

including initializing system

producing key

distributing key

and transmitting data securely

are described.This solution solves small storage and weak compute capability problems. It is matched to the processing power of terminal equipment of RFID.The study shows that the approach has some important features

such as small storage

high security and high running efficiency.And it provides new means for key management of RFID.
