Abstract

Digital forensics is a fast-growing €field involving the discovery and analysis of digital evidence acquired from electronic devices to assist investigations for law enforcement. Traditional digital forensic investigative approaches are o‰ften hampered by the data contained on these devices being encrypted. Furthermore, the increasing use of IoT devices with limited standardisation makes it difficult to analyse them with traditional techniques. ŒThis paper argues that electromagnetic side-channel analysis has signi€ficant potential to progress investigations obstructed by data encryption. Several potential avenues towards this goal are discussed.
