Andreas Renz

His research is in applied cryptography: two peer-reviewed papers in usable security, and a self-published technical report on post-quantum zero-knowledge proof systems. The work is indexed under ORCID, dblp and Google Scholar.

He writes nonfiction about post-quantum cryptography at encryptorium.com, under the handle 0xLoopTheory: signatures, key exchange, protocol analysis, and the practical side of systems that shouldn't break.

His debut novel, Cleartext, is a near-future techno-thriller set against the migration to post-quantum cryptography. It follows the people who spend their careers securing the infrastructure most of the world never thinks about until it fails. The book draws on his work in applied cryptography and cybersecurity, where the gap between theoretical soundness and deployed reality is where most of the interesting problems live.
