Sistem Keamanan Pesan Teks pada Email Menggunakan Algoritma Triple Transposition Vigenere Cipher (TTVC) dan RSA

Abstract

Progress development of information systems increasingly so quick. Theres so many important document has been send by internet However, development of information technology as it also causes exchanged of information or messages not safe anymore. hackers exploit the insecurity gap to enter and manipulate messages or information has been changed. For example, can lead to leakage and data corrupt. So need more security techniques for maintaining the confidentiality and security of information or messages. To resolve this problem can be solved by using a combination of cryptografi algorithms. By applying the RSA asymmetric cryptography system and symmetric cryptography Triple Transposition Cipher Vigenere. Based on the testing that has been done, the combination of the combination of the RSA algorithm and the Triple Transposition Cipher Vigenere can secure text messages that have been sent because use the iteration process three times using three key transposition and substitution of three different and combined with the RSA algorithm.
