A chat message has high privacy and there are still many chat applications that do not provide security so the messages can be intercepted and known by unwanted people. AES cryptography has generally been implemented in most chat messenger applications. However, with cases of eavesdropping and fraud still rampant, it is necessary to improve message security schemes that can strengthen the security and the authenticity of messages. This study aims to combine AES cryptography and digital signature in securing mobile-based chat messengers so the scheme can secure messages in terms of security and authenticity of text messages. This study uses text consisting of 10 to 100 message characters. From the results of the tests, it can be concluded that AES cryptography and digital signature is considered good for securing text messages because the Avalanche Effect value is following the Strict Avalanche Effect standard. With the addition of a digital signature method, it can improve message security for the better because the authenticity of the message can be guaranteed with an insignificant increase time compared to using only AES cryptography with the average time required for the security process using AES cryptography is 6.71 ms and 6.54 ms, while the average time required for the security process with the addition of the digital signature method is 7.54 ms and 7.19 ms.
