Dear colleagues, I am happy to announce the publication of my book with Ksenia Ermoshina, "Concealing for Freedom: The Making of Encryption, Secure Messaging and Digital Liberties" (Mattering Press, April 2022, with a foreword by Laura DeNardis). The book is released in open access and available here in a variety of digital formats: https://www.matteringpress.org/books/concealing-for-freedom Please consider however to buy a paper copy if you or your university library can do so, it will help Mattering Press to thrive. The publication is accompanied by a blog post that reflects on the relationship of phenomena and events described in the book to current events: https://www.matteringpress.org/blog/encryption-and-technologies-of-power-in-...
