Sandia develops secure wireless technology using AES and UWB
This article describes a secure form of wireless sensor communication which "leverages UWB with the unyielding encryption protection of the 256-bit Advanced Encryption Standard (AES) to form UWB/AES". Among the key wireless features of the UWB/AES are its IP network compatibility and its â€œper-packetâ€ 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.
A recent test moved streaming video over such a link, using only microwatts (compared to milliwatts for 802.11b/g) of RF power. Sounds almost too good to be true... UWB is expected to hit the market in 2005 according to this 2002 article and this 2004 article . Oops, OK, maybe 2006? Whenever, it will be big. Companies like Freescale are developing UWB chips which were/are due Real Soon Now.
