No More Woof is a wearable brainwave-reading headband for dogs that can interpret up to four neural patterns and voice them in human-speak.
Be afraid, friends, for science has given us a new way in which to circumvent some of the strongest encryption algorithms used to protect our data -- and no, it's not some super secret government method, either. Researchers from Tel Aviv University and the Weizmann Institute of Science discovered that they could steal even the largest, most secure RSA 4,096-bit encryption keys simply by listening to a laptop as it decrypts data.
To accomplish the trick, the researchers used a microphone to record the noises made by the computer, then ran that audio through filters to isolate the vibrations made by the electronic internals during the decryption process. With that accomplished, some cryptanalysis revealed the encryption key in around an hour. Because the vibrations in question are so small, however, you need to have a high-powered mic or be recording them from close proximity. The researchers found that by using a highly sensitive parabolic microphone, they could record what they needed from around 13 feet away, but could also get the required audio by placing a regular smartphone within a foot of the laptop. Additionally, it turns out they could get the same information from certain computers by recording their electrical ground potential as it fluctuates during the decryption process.
