암호학적 관점에서의 EWF 파일 이미징 효율성개선 방안 연구

Compared to the past, the current disk storages have dramatically increased and extremely many data are transferred on the network everyday. In spite of the anticipation that such development will be continued, there have been lack of studies for improving the data-imaging time in terms of the digital forensics. In this paper, we firstly investigate the time due to hash functions during the data Imaging and secondly propose a method for improving the efficiency of the EWF-File imaging time from a cryptographic perspective
