Perancangan Dan Implementasi Algoritma Enkripsi One Time Pad Untuk Sistem Keamanan Pembelian Dan Penjualan Produk Pada PT. Nuga Agara Internasional

Abstract

The problem of computer security and data privacy, something very important in this information era. Confidentiality of data is very important in data security. There are some commonly used encryption algorithms like DES, Triple DES, Blowfish, IDEA, One Time Pad, etc. The algorithms are very complicated and difficult to understand, on the pretext of "safety factor '", they said the more difficult one to understand the more secure algorithm. However, for those users they do not think about how difficult algorithms, which are important data safe. For the protection of important data that there is no other way besides using a method known as data security or cryptography techniques. In General, cryptographic techniques used to perform data encryption and authentication data. To do this, use an encryption method one time Pad for security in information system product sales and the purchase in PT. Nuga Agara Internasional.
