Abstract— One of the facilities provided by cellular phones is to send data in the form of short messages via Short Message Service (SMS). Most people use SMS services more often than phone services because they are cheap and easy to use. Open networks, easy access, standard platform and open source development bring security threats such as viruses, phishing, spam on SMS. Security information in SMS can be done by encrypting messages to be sent. The AES (Advanced Encryption Standard) algorithm is a standard for data encryption, suitable for scenarios where memory and processing capabilities are very limited as in mobile devices. Encryption for text data types can also use the Blowfish algorithm, where the Blowfish algorithm can perform encryption and decryption with better performance compared to other symmetric algorithms if packet data size changes. The results of the study showed that the AES method was the fastest in SMS encryption and decryption while the Blowfish method changed the number of characters from the SMS sent at least.
