نویسندگان
چکیده
Dalam penyimpanan data, dokumen pengiriman disimpan tanpa pengamanan khusus. Untuk mengatasi masalah di atas, diperlukan cara yang cepat untuk melindungi data dari penyalahgunaan. Peneliti bertujuan menggunakan teknik enkripsi deskriptif algoritma AES 128-bit pada sistem, karena memiliki tingkat ketahanan tertentu terhadap segala jenis serangan menghindari kehilangan dan pencurian serta mengurangi risiko korupsi data/file. Proses deskripsi file (Advanced.Encryption Standard ). Pada data/file, proses plaintext (1 blok) terlebih dahulu diubah menjadi kode ASCII bilangan heksadesimal dibentuk matriks 4x4 byte disebut state . 128 adalah 10 loop iteratif transisi Data diproses setiap putaran biner Setiap membutuhkan pembangkitan kunci 4 transformasi dasar, yaitu subbyte, shiftrows, mixcolumns, addroundkey. Dan dekripsi mengkonversi dalam urutan invshiftrows, invsubbytes, addroundkey, invmixcolumns. Pemrosesan dilakukan bit atau 16 karakter dengan lebih dikonfirmasi. Jadikan paralel. teks kurang karakter, padding akan terjadi. Padding penggunaan kosong mengisi sejumlah kecil sehingga dapat mempengaruhi hasil dekripsi.

متن کاملOperation Shipping for Mobile File Systems
This paper addresses a bottleneck problem in mobile file systems: the propagation of updated large files from a weaklyconnected client to its servers. It proposes an efficient mechanism called operation shipping or operation-based update propagation. In the new mechanism, the client ships the user operation that updated the large files, rather than the files themselves, across the weak network....

It is now clear that the two broad sets of reactions in the ubiquitin-proteasome system (UPS), the conjugative and degradative steps, are intricately coupled in vivo and that there are numerous factors that aid in the handling and delivery of ubiquitylated proteins to the proteasome. The report from Richly et al (2005)[this issue of Cell]) suggests how several of the known players in this proce...
