Abstract

Mobile device or known as smartphone have a role for human communication. Everyone can communicate even if they in long distance with using smartphone. But, the crime in digital communication keep happening.  On of them is tapping. Tapping is a action to monitoring an information that sent by unauthorized people of that information. A way to solve tapping is do cryptography to informatin to be sent. Cryptography is generally devided into two things, that is encryption and decryption. Encryption is a process to convert a text into another format. Meanwhile, decryption is a process to convert back a information that has encrypt into original form. One of cryptography algorithm is symmetrical algorithm, which is an algorithm that uses the same key for the encryption and decryption process. Therefore, message cryptographic application are designed using symmetrical algorithm. The analytical technique used is Unified Modeling Language (UML) to modeling the system. In system designed, author using MySQL for database design dan using Android Studio as an Integrated Development Environment (IDE). From this entire research process, is expected can resolve tapping of the information that send by user. Keyword: application, cryptography, encryption, decryption, key
