Abstract

Kriptografi dapat dibedakan menjadi 2 yaitu kriptografi dengan menggunakan kunci simetri dan kriptografi dengan menggunakan kunci asimetri. Contoh kriptografi kunci simetri adalah 3DES (Triple Data Encryption Standard) dan kriptografi kunci asimetri adalah RSA. Pada aplikasi ini penulis memodifikasi metode 3DES (Triple Data Encryption Standard) sehingga pengamanan terhadap text dapat lebih aman dibandingkan 3DES. Modifikasi metode 3DES yang dilakukan menghasilkan ciphertext yang lebih panjang dan ada penambahan proses pada proses enkripsi dan dekripsinya.

 

Cryptography can be divided into 2 key cryptography using symmetric and asymmetric key cryptography using. Examples of symmetric key cryptography is 3DES (Triple Data Encryption Standard) method and asymmetric key cryptography is RSA method. In this application, the authors modified the method of 3DES (Triple Data Encryption Standard) so that the security of the text can be more secure than 3DES method. Triple DES modification method produces cipher text that is longer than 3 DES and there are additional processes on the encryption and decryption process.
