Researchers in the 🇳🇱 Netherlands found serious flaws, including a deliberate backdoor. Three (3) Dutch security analysts discovered the vulnerabilities - five (5) in total - in a European #radio standard called TETRA. The standard has been used in radios since the ’90s, but the flaws remained unknown because encryption algorithms used in TETRA were kept secret until now. #crypto #europe #telecom #vuln [ https://www.wired.com/story/tetra-radio-encryption-backdoor/ ] #informatique

Brian Murgatroyd, chair of the technical body at ETSI (etsi.org) responsible for #dev the TETRA standard and algorithms, spoke with Kim about why his standards group weakened an #encryption algorithm used to secure #critical radio communications of #police, #military, #government, critical #infrastructure and others.

« The researchers are calling it a #backdoor because the reduction isn't a glitch ; the algorithm was designed this way to make it intentionally weak » #ict #telecom #technologies [ https://zetter.substack.com/p/interview-with-the-etsi-standards ]
