David A. Wheeler has described a technique called “Diverse Double-Compiling”, for which it is claimed that it fully counters the attack described in Ken Thompson’s classic paper “Reflections on Trusting Trust”. While it seems an interesting technique, with some potential practical application, it does not seem to me that it reliably detects the Thompson attack – indeed it seems to me that the DDC papers re-inforce the point made by Thompson about trust. I’ve written up these thoughts in a short paper here.
