Hash Equations and Cryptographic Applications on Forensic
Muhammet Tahir GÜNEŞER Hacı Hasan OKUYUCU
AbstractForensic computing is a new branch of science created to facilitate the decision of the investigator in the case by examining the evidence obtained in the information systems. In forensic computing, all devices in hand have a data summary value (hash). Hash is a numerical value and unique given by the investigator so that evidence can be considered as evidence in the court by preventing the integrity of the evidence. In accordance with Article 134 of the Criminal Procedure Law (CMK), this numerical value, which is unique to the evidence, should not be altered in any way. If it changes, the evidence in question is no longer evidence, and it will not be taken into consideration by the investigating authority even if it gives a clue about the suspect. In this study, we expressed hash applications on forensic and the calculation methods of this numerical value which has great importance while judgement.
