By Howdy Pierce
I just read a report of a new IP security vulnerability being demonstrated today at the DefCon hacker’s conference in Las Vegas. The new hack has two components:
1. The attackers are able to view video being streamed across a network, and
2. The attackers are able to use a man-in-the-middle attack to insert video controlled by the attacker to a video decoder somewhere on the network.
The linked video shows viscerally how an attacker could foil a security/surveillance video system — a modern-day Thomas Crown Affair. Details
Power Measurements With the DFT
By Mike Perkins
Many of the systems we work on here at Cardinal Peak employ analog-to-digital conversion in one form or another. It seems like almost invariably some analog signal needs to be digitized or “sampled.” Sampling is the process of periodically looking at an analog signal at some sample rate, and then converting each measured value into… View ArticleDetails
