Digital crime and forensics research has taken an unprecedented step forward in the past decade, research scientists from all over the world have contributed tremendously to the progression of digital security and forensics. However a slew of problems are still existential in the relevant fields especially in mathematical modelling, intelligent computations and evaluations, etc. The focus of this workshop is on calling up the interesting group who dedicated to this area and resolving those thorny problems. This inaugural workshop will endow to mathematical modelling and evaluations of security algorithms. The research work has taken substantial achievements in any security computing areas will be awarded. This workshop will be backed up by the International Journal of Digital Crime and Forensics (IJDCF) and jointly organized by the Key Laboratory of Intelligent Network and Network Security of the Ministry of Education (MOE) of China at Xi’an Jiaotong University and the State Key Laboratory of Information Security (SKLOIS) of China at Chinese Academy of Sciences (CAS).
