CIS sought to file a friend-of-the-court, or “amici curiae,” brief in the case today. We submitted the brief on behalf of a group of experts in iPhone security and applied cryptography: Dino Dai Zovi, Charlie Miller, Bruce Schneier, Prof. Hovav Shacham, Prof. Dan Wallach, Jonathan Zdziarski, and our colleague in CIS’s Crypto Policy Project, Prof. Dan Boneh. CIS is grateful to them for offering up their expert take on the serious implications of the court’s order for the entire security ecosystem. We hope the court will listen.
