One of the strangest moments at the Black Hat USA security conference in Las Vegas this month has now become the subject of a federal lawsuit against the conference.

In a filing to the United States District Court for the Southern District of New York (PDF), attorneys for the "emerging digital cryptography" firm Crown Sterling alleged that Black Hat USA had breached "its sponsorship agreement with Crown Sterling and the implied covenant of good faith and fair dealing arising therefrom." Crown Sterling goes on to accuse the conference organizers of "other wrongful conduct" connected to events surrounding the presentation of a paper by Crown Sterling CEO and founder Robert E. Grant. In addition to legally targeting the conference, Crown Sterling has also filed suit against 10 "Doe" defendants, who it claims orchestrated a disruption of the company's sponsored talk at Black Hat.
