Sandia Labs: UWB & AES demo for next generation secure wireless networks
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.
