1 year ago@cosmo @stefenauris @bersl2 agree except that TEA2/3 weren’t vulnerable *in this particular study*. ETSI/TCCA are (foolishly, I think) sticking to their guns on the algorithms being tightly controlled. Without proper, widespread academic scrutiny there is little confidence that they are *actually* secure.
@cosmo @stefenauris @bersl2 I like how the researchers in their release squarely blame the TEA1 issues on failure to adhere to Kerckhoffs’s principle; but ETSI in their response completely fail to address that and adopt a “this is fine” stance.
