Removing RSA keys by acoustic cryptanalysis

  Image from: xkcd The famous cryptographer Adi Shamir and his colleagues published a scientific paper titled "RSA Key Extraction via Low-Bandwidth Acoustic Cryptanalysis" Many computers emit high frequency sound during operation, because of the vibrations in some electronic components (capacitors) caused due to microscopic variations in the voltage of...

The TrueCrypt Audit

Given the recent news about NSA's ability to foil encryption soft wares, cryptographer Matthew Green and Kenneth White has started an initiative to examine the Truecrypt disk encryption tool. Why does it matter? Since NSA has been snooping in our data without us knowing, decryption of SSL connections and tampering with established standards to... [Read More]
