PENERAPAN ALGORITMA HILL CIPHER PADA PERANCANGAN APLIKASI KRIPTOGRAFI BERBASIS ANDROID

Abstract

Cryptography is the study of mathematical techniques related to aspects of information security, such as data confidentiality. Users have limitations in the delivery of messages confidental. Therefore, the authors is interest to make a Android based cryptographic applications that can be used for encryption and decryption of data messages so that the message data is secure. Users of Android based cryptographic applications also could send messages in the form of a message that has been encrypted. Users of Android based cryptographic applications can be used by the sender and the recipients of the message in the same application. Cryptographic application use hill cipher algorithms. Hill cipher algorithms has a matrix multiplication process. Matrix multplication is used in the encryption and decryption of data messages. Keywords : Cryptography, Hill Cipher, Android, Algorithm, Matrix.
