Sandia 發展的 UWB/AES 技術
剛剛閱讀這篇新聞 [
Sandia develops secure wireless technology],或許可以作為下個世代無線網路的雛型。Sandia National Laboratories 與其合作的 Time Domain Corporation 和 KoolSpan Inc. 正在建構以 UWB (Ultra Wideband) 為骨幹的無線網路技術。以往,無線網路最令人詬病之處,就在於安全性,而 Sandia 則將 UWB 與加密標準的 AES (256bit) 整合在一起,此外,也提到對於 RF 的改進,至於目前的成效來說,引述報導原文:
Among the key wireless features of the UWB/AES are its IP network compatibility and its “per-packet” rotating 256-bit encryption keys for even greater crypto-protection. The UWB/AES network architecture requires no computing infrastructure, provides real-time (hardware) encryption, and requires zero maintenance for complete self-recovery if interrupted or when a sensor goes down.
而且就實際的測試項目來看,只需要傳統 802.11b 或 WiFi 的千分之一的功率。
