Security is very important in all aspects to protect data. Text messages on mobile phones, which is sms (short messages service) is one of the important data that needs a data security system. Data security is used to maintain the confidentiality of important data that we have on mobile devices. The encryption process is used so that messages cannot be read by other unwanted parties. While the decryption process is used so that the message can be read back by the intended party. Rivest Cryptography, Shamir, Adleman (RSA) is one of the asymmetric cryptographic algorithms that use a key pair, that is the public key and private key. The key length can be set, where the longer the key formation bit, the harder it is to solve because it is difficult to factor two very large numbers. This study applies the Rivest, Shamir, Adleman (RSA) algorithm for text message security applications based on Android. Based on the research that has been done, the author can draw conclusions, namely: Rivest, Shamir, Adleman (RSA) cryptographic algorithm can be implemented for text message security Android based. So it is safer to exchange text messages (SMS) so that user privacy is guaranteed
