Computer Simulation of Group 3 Facsimile Encryption

摘要

The purpose of this study was to determine the error sensitivity of Group 3 facsimile systems in which the Data Encryption Standard (DES) encryption algorithm is employed to provide the secure transmission of binary documents. This report presents the results of a computer simulation study in which the effects of transmission errors on the performance of Group 3 facsimile employing the DES encryption algorithm were examined. Section 1 provides a brief description of the objectives of the study and contains a synopsis that outlines the results and conclusions obtained. Section 2 presents the technical approach employed in the study and includes a discussion of the system analysis performed, the simulation methodology employed, and detailed descriptions of the compression, encryption, and error signal algorithms simulated. The results of the simulation study are presented in Section 3. The conclusions made based on these results are contained in Section 4. (kr)
