Encrypted mobile phones are often a key factor in criminal cases; the data stored in these devices may contain critical evidence. With most telephones protected by encryption, the rapid processing of critical evidence by various information retrieval techniques is slowed down, if not made impossible. EXFILES will use software exploitation, hardware methods and combined methods to give law enforcement officials the tools and protocols for rapid and consistent data extraction in strict legal contexts. Tools and methods inspired by other areas of information security (e.g. security assessments based on common criteria) will lead to new judicial methods of accessing data for lawful investigations. EXFILES will focus on the ethical and legal aspects of research and exploitation as well as dissemination and training activities for the next generation of forensic experts.
