Modifikasi Fungsi F dalam Algoritma Camellia dengan Mengulang Langkah dalam Fungsi F

Abstract

Progress and development of information technology has an effect on almost every aspect of human life, not least in terms of communicating. The most frequently encountered issues in communication is information tapping. Therefore, a system of encoding information such as cryptography security to develop. In many cryptography algorithms are used as the basis for the encoding of information is the Camellia algorithm developed by the NTT and Mitsubishi from Japan. Therefore, in this thesis the author will conduct research and analysis of the Camellia algorithm to modify the Camellia algorithm so as to get a new algorithm results from the modification of the Camellia algorithm. And of these algorithms will be implemented in the application form. Based on the results of the testing, the application has been running well and can meet the needs of authors, but the application still has weaknesses in aspects of data conversion.
