on 02022-09-16#security Russ Cox says: “For the record, back in 2013, Ken told me that the backdoored compiler did in fact exist and was deployed, but it had a subtle bug that exposed the backdoor: the reproduction code added an extra \0 to the string each time it copied itself. This made the compiler binary grow by one byte every time it rebuilt itself. Eventually someone noticed and debugged what was going on, aided by the fact that the “print assembly” compilation mode did not insert the backdoor at all, and all traces were cleaned away. Or so we believe.”

on 02021-11-02looks like lowRISC’s #OpenTitan is from ETH Zürich, #Google, Western Digital, Seagate, ... and something called G+D Mobile Security and Nuvoton? But their Git repo is largely written by Michael Schaffner (Google), Eunchan Kim (Google), Cindy Chen (Google), Philipp Wagner (lowRISC), Timothy Chen (Google), Silvestrs Timofejevs (lowRISC), and Pirmin Vogel (ex-ETH, now lowRISC). The initial commit, “Start of public OpenTitan development history”, lists 19 contributors, 13 of them at Google. So basically it’s a Google project. They explain, “By creating OpenTitan with the broader hardware and academic community, we leverage the experience and #security principles used to create Google’s Titan chips to make #hardware root of trust designs more transparent, inspectable, and accessible to the rest of the industry.”
