Key Reminiscences

I offer some reminiscences about work by Cathy Meadows as well as about working with and for Cathy Meadows. I also recall cryptographic protocol properties introduced in our work in the 1990s and show their applicability to analyzing novel protocols today. Specifically, I describe a recent protocol [8] for anonymous proof of account ownership using the novel primitive of secure channel injection (SCI). And I describe how the claim of transcript privacy for a specific SCI protocol depends on an implicit and not necessarily justified assumption of key virginity. I also discuss ways to modify the protocol to achieve intended goals.
