pada Android
Rapid development in mobile phone technology recently has caused the
emergence of smart phones with many different features, and a complex operating
system just like a computer. One of well known operating system for mobile
phones is android. Nonetheless, although these new technology of smart phones
have many features, people seems still has a special attention to an old-fashioned
text service, which is Short Message Service, better known as SMS.
Unfortunately, SMS feature nowadays still has limitations. Especially regarding
the safety of confidential information. In other word, the ability of someone in
sending a confidential information through SMS is still in question. In order to
solve this kind of problem, authors will try to create an application that capable to
secure a confidential message.
Security system that author offered is based on two security models,
namely encryption and steganography security. Before being sent, a message will
firstly encrypted using the Caesar cipher algorithm, and then inserted into the
SMS text messages using the algorithm whitespace. Next, an access to the
message in the application must be secured with a password, so the message will
be safe from unauthorized parties.
The research methodology used in this research is the development of the
operation system. The research steps is begins with library study, identifying
system requirements, data collection, system requirements, and system
development methods.
Then, finally, this research will able to create an applications that will be
installed on Android-based smart phones. This application can do the Caesar
cipher encryption algorithm, and will hide it in a text message or SMS. The results
of encryption and steganography process to the message is also can be decrypted
through this application by entering a preceding password.
Keywords: encryption, steganography, information security, whitespace, Caesar
cipher.
