The further study on the current models of electronic forensics,an electronic judicial identification model based on three-dimensional trusted electronic evidence acquisition model is proposed.The model implements linear process control,evidence supervision,time constraints and legal constraints and trusted fix of electronic data for the whole process of judicial identification.By establishing political and judicial certification authority,it achieves mutual trust and mutual recognition between relevant agencies and the court in the whole process of evidence collection and identification,and ensures their own safety and legal effect on evidence supervision chain.At last,it verifies the correctness of the model by case analysis.
After an introduction of the traditional fix method of digital data,in view of trusted forensics,a framework and its corresponding trusted fix method which supports the digital data's static properties is provided.Using DSA digital signature,timestamp,and the third confirmer signature scheme,the specific trusted fix algorithm of digital data is studied.Via formalized analyzing,the constraint rules for the digital data's static properties have been defined to be trusted,which also supports to the trusted fix.At last,with introduced axioms,theorems and rules,the formalized analyzing of trusted forensics is validated by certain examples.
