Abstract

Text message security can be maintained by using cryptographic techniques. The purpose of cryptography is to make text messages that are sent difficult to read by third parties, these messages can only be read by authorized people. By using a combination of the Caesar cipher and One Time Pad (OTP) Algorithm for Text Message Security using ASCII tables, which is the text messages will be encrypted first with the Caesar Cipher algorithm then the results (ciphertext) will be re-encrypted using the One Time Pad (OTP) algorithm. Then the decryption process will be carried out using the One Time Pad algorithm first, then the results (plaintext) will be decrypted again using the Caesar Cipher algorithm. The results of the message decryption test return to the original message (plaintext) using the same key from the encryption process.
