Cryptography on Android Message Application Using Look Up Table and Dynamic Key (cama)
Most popular shortest and cheapest textual form of communication is Short Message Service (SMS).To ensure the security of the texts which is sent, many algorithm are available. In this paper, the authors propose an efficient algorithm for cryptography which is based on static Look Up table and Dynamic Key. Symmetric encryption and decryption is used in this algorithm. The proposed algorithm is more secure and simple to implement. This application makes use of built in android Intents and SMS Manager to send and receive messages.
