Abstract

Abstract - The very rapid advancement of telecommunication technology has provided many benefits. With this technology, long distance communication is not an obstacle. One technology that is always used is the sender of messages. At this time, the message application has been used by the community to convey messages to the recipient, the community uses the message application as a communication tool to send messages, the information provided is more precise and is a satisfaction in itself because using message sending application technology is more efficiently received to the recipient. Message content; constitute; security, social, education and professional and entertainment. In history, the Shift Chiper was used during ancient Rome, namely Julius Caesar. the technique used is very simple, namely by shifting each letter in its diplaintext. The main principle of the substitution cipher is to replace each letter on the plaintext into something. Substitution ciphers are incorporated into classical cryptographic algorithms. The idea is to replace one or more letters in plaintext with one or more letters in plaintext with certain rules. These rules are based on the encryption and decryption process. The substitution cipher has many variants or types.

Abstract

Currently, especially in the development of information technology is developing so rapidly. Safeguarding and protecting informational text messages from various parties that can harm is very important. Maintaining informed text messages has a science, like cryptography. Cryptography in text messages to protect important data so as not to harm the owner. Therefore, we need to improve text messaging, especially data such as document files and text messages. So, the authenticity of the data can be maintained safely. The combination of cryptographic algorithms used to secure text messages is the Caesar Cipher algorithm and the Permutation Cipher algorithm. So, by using a combination of the caesar cipher algorithm and the permutation cipher algorithm, the security level of text messages can be more maintained for the authenticity of the data.
