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.

许多学者针对这些安全议题，提出了具隐私保护的RFID协定，期望能解决隐私性问题，但是这些协定大都是依靠一个On-Line的后端伺服器作处里，无法在Off-Line的环境底下运作。

They allow that the backend server could delegate the reader to identify the tag information. But the Fouladgar and Afifi's SiDES protocol will suffer from the replay attack, forgery attack, Denial-of-Service attack and fail to achieve the forward security. Although Lin's protocol uses timestamp to control the delegation, it does not keep forward security property under the same time frame.

在2007年，Fouladgar和Afifi首先提出了离线式SiDES协定，接著Lin也提出了TCD-RP协定，可让后端伺服器可以授权读取器辨识标签的资讯，但Fouladgar和Afifi的SiDES定理，会遭受重送攻击、伪造攻击、阻断服务攻击以及不具有向前安全性的特性；而Lin的协定虽然使用时戳来做授权的控制，但在相同的时间区段下运作，并不具有向前安全性的特性。
