چکیده
Penggunaannya yang kian massif dan banyakya data informasi tersebar di internet mungkin saja terdapat bersifat rahasia, menjadikan tersebut rawan untuk disalahgunakan dari tindakan illegal oleh pihak tidak bertanggung jawab. Faktor keamanan menjadi hal sangat penting agar tetap aman terjamin keasliannya. Maka dibutuhkan metode asli. Kriptografi adalah mengamankan digital dengan cara mengubah mengacak asli (plainteks) bentuk dikenali (cipherteks). itu dipilihlah menggunakan kombinasi algoritma vigenere AES dalam Vigenere digunakan sebagai pembangkit kunci karena aman, cepat banyak menghabiskan sumber daya, menghasilkan ciphertext bervariasi. dipilih akan mengenkripsi file dokumen sistem cycle atau putaran, bervariasi terhadap panjang kunci. Sehingga ketika variasi berbeda, jumlah putaran disesuaikan. Dengan adanya program ini diharapkan dapat membantu menyembunyikan Berdasarkan hasil eksperimen pada proses enkripsi dekripsi, dihasilkan nilai Avalanche effect cukup baik. Nilai Aevalache Effect diperngaruhi pajnag digunakan. Pada Analisa kebutuhan waktu diketahui bahwa dekripsi pesan membutuhkan lebih lama disbanding enkripsi.

Generalization of Vigenere Cipher
A generalized way of Vigenere cipher is proposed. Instead of using a Vigenere square for encryption and decryption, any two reversible square matrices whose rows or columns are unique are used for encryption and decryption purpose. One matrix can be easily obtained from the other and hence any one of them can be used for encryption while the other can be derived from the other for decryption. T...
متن کاملFPGA Can be Implemented Using Advanced Encryption Standard Algorithm
This paper mainly focused on implementation of AES encryption and decryption standard AES-128. All the transformations of both Encryption and Decryption are simulated using an iterativedesign approach in order to minimize the hardware consumption. This method can make it avery low-complex architecture, especially in saving the hardware resource in implementing theAES InverseSub Bytes module and...
متن کاملAn Improvement of RC4 Cipher Using Vigenere Cipher
This paper develops a new algorithm to improve the security of RC4. Given that RC4 cipher is widely used in the wireless communication and has some weaknesses in the security of RC4 cipher, our idea is based on the combination of the RC4 and the poly alphabetic cipher Vigenère to give a new and more secure algorithm which we called VRC4. In this technique the plain text is encrypted using the c...
متن کاملAdvanced Encryption Standard
The Advanced Encryption Standard (AES), which implements the Rijndael cipher, is a symmetric block cipher that was developed as a result of a call by the United States National Institute of Standards and Technology in 1997 for a secure cryptosystem to replace the then standard Data Encryption Standard algorithm, which had become vulnerable to brute-force attacks. Among several proposals, the Ri...
متن کاملImage Encryption Using Advanced Hill Cipher Algorithm
The Hill cipher algorithm is one of the symmetric key algorithms that have several advantages in data encryption. But, the inverse of the key matrix used for encrypting the plaintext does not always exist. Then if the key matrix is not invertible, then encrypted text cannot be decrypted. In the Involutory matrix generation method the key matrix used for the encryption is itself invertible. So, ...
