JURNAL: IMPLEMENTASI STEGANOGRFI DENGAN PENGGABUNGAN KRIPTOGRAFI METODE VINEGERE DAN CAESAR SUBSITUTION

Abstract

Data security is very necessary to maintain a critical and confidential data. One method used is data encryption techniques, which in the know with the science of cryptography. In this way the original data is encoded or the encryption to confidential data so that data will not be meaningful to an unauthorized person who managed to access the assets or information. Among the methods that use cryptographic algorithms are the algorithm vinegere and caesar subtitution. Research data security is a title in the combined algorithm and caesar subtitution vinegere LBS method into an application is mutually beneficial to secure the txt file where the txt file as the original data encrypted with vinegere and after that the encryption back to the methods section. This research was conducted by collecting information with literature methods, methods of documentation and observation methods. Following information were obtained, we then conducted data analysis and system requirements. After the analysis phase is completed followed by a design which consists of designing application context diagram, DFD design (data flow diagrams), design flowchart and interface design. After the design phase is completed and then forwarded to the implementation of program testing program. The results of this study is a security application data using algorithms vinegere and caesar subtitution. This application is able to encrypt a txt text file. Results of testing the success rate of encryption and decryption of the application obtained by the percentage of 100% as expected. Based on the testing program can be concluded that this application useful and handy to keep your data secure files. Txt.
