Analisis Perbandingan Algoritma NGG dan GGHN pada Frekuensi Hasil Enkripsi

Data and information in the development of digital technology have an important role. Every activity or that uses is related to data information, so security confidentiality are very important. To maintain confidentiality, protection with cryptographic techniques needed. Cryptographic encryption, which where process scrambling carried out hiding a key system, while decryption changing condition its original form it easy understand. There obstacles problems ini communication, needed higher level can be applied communications. determine required frequency anlysis. Frequency analysis on NGG GGHN algorithms based results encryption. BAse testing algorithms, will known characters text varies. The more used affect security. algorithm has than precentage difference 0.000299967%. If occurrence message been encrypted frequent higher, then lower password easier crack.
