Therefore, this thesis designs a more secure RFID protocol to fix these security flaws. In 2007, Fouladgar and Afifi also proposed EDTOP protocol which is based on AES and keeps higher performance on the operations of tag ownership transform. However, it also fails to achieve the forward security. Therefore, this thesis further proposes an improved protocol which can achieve the forward security.

However, most protocols are relying on one on-line backend server and cannot work on an off-line environment. In 2007, Fouladgar and Afifi first proposed the off-line SiDES protocol. Later, Lin proposed a TCD-RP protocol.
