文章基于FPGA设计了一种能完成AES算法加密的密码协处理器，设计中利用VirtexII系列FPGA的结构特点，对AES算法的实现做了优化。

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.

因此吾人在本论文里，设计一个更安全的RFID协定，来改善这一些问题。2007年，Fouladgar和Afifi又提出了一个植基於AES运算和具高效率的标签所有权转换的协定EDTOP，但是吾人发现EDTOP协定并不具有向前安全性的特性，所以在本文中提出了一个植基於AES且具有向前安全性的RFID标签认证协定。

The CO/Fe/TiO〓(110) system has been studied using AES, ISS, LEED, UPS, WF and HREELS. AES results showed that the growth of the deposited Fe overlayer on the TiO〓(110) surface follows the layer-by-layer growth model.
