In public, this may be a problem. However, this type of situation is exactly what TEMPEST is meant to mitigate. But, defense and intelligence have a much different threat model than most commercial shops or producers of consumer electronics.</P> Mon, 29 Oct 2018 16:29:02 GMT Badfilemagic 2018-10-29T16:29:02Z https://community.isc2.org/t5/Tech-Talk/Screaming-Channel-attack-and-no-I-m-not-talking-about-US-Cable/m-p/15892#M559 <P>Saw some recent traffic here regarding secure development and IoT vulnerabilities.&nbsp; I just read a <A title="Screaming Channels: When Electromagnetic Side Channels Meet Radio Transceivers" href="https://dl.acm.org/citation.cfm?id=3243802" target="_self">paper</A> discussing&nbsp;a recently studied problem between mixed-signal chips and the inherent electromagnetic leakage that comes with them.&nbsp; The authors were able to demonstrate a complete key recovery attack to recover the key used by an AES-128 implementation at a distance of 1m.&nbsp; Anyhow, just wanted to share with <a href="https://community.isc2.org/t5/user/viewprofilepage/user-id/310811187">@ontheway</a> and the rest of the community.</P> Mon, 09 Oct 2023 08:59:53 GMT https://community.isc2.org/t5/Tech-Talk/Screaming-Channel-attack-and-no-I-m-not-talking-about-US-Cable/m-p/15892#M559 DAlexander 2023-10-09T08:59:53Z https://community.isc2.org/t5/Tech-Talk/Screaming-Channel-attack-and-no-I-m-not-talking-about-US-Cable/m-p/15928#M565 <P>The key material recovery aspect is indeed intriguing, but luckily the 1m distance forces the adversary close-in.
