Implementation of combined steganography and cryptography vigenere cipher, caesar cipher and converting periodic tables for securing secret message

Abstract The development of the communication technology era has made it easier in process exchanging information from various parties. However, not all provided can be used by many Sometimes is intended for partial purposes only or confidential. So, necessary to security. Several ways such as cryptography. This method encrypt messages information. Methods that cryptography include vigenere cipher and caesar methods. Both these methods use technique replacing each original character with a letter. Substitution based on keywords position shift command. this quite easy solve using Brute Force frequency letters often appear. Based problem, modify combine so more difficult crack. research describes combination two were then converted names chemical elements periodic table. Furthermore, steganography carried out place insert From process, expected encryption results will crack
