For AES-128, the key can be recovered with a computational complexity of 2 126.1 using the biclique attack. For biclique attacks on AES-192 and AES-256, the computational complexities of 2 189.7 and 2 254.4 respectively apply. Related-key attacks can break AES-256 and AES-192 with complexities 2 99.5 and 2 176 in both time and data, respectively.
Advanced Encryption Standard process. The Advanced Encryption Standard (AES), the symmetric block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using a process lasting from 1997 to 2000 that was markedly more open and transparent than its predecessor, the Data Encryption ...

V 2 O 5 + 6 NaOH → 2 Na 3 VO 4 + 3 H 2 O. The salt features tetrahedral VO 3− 4 anion centers linked to octahedral Na + cation sites. Condensation equilibria. Like many oxometalates, orthovanadate is subject to a number of reactions, which have been analyzed by 51 V NMR studies. At high pH, VO 3− 4 ions exist in equilibrium with HVO 2− 4.

Se + 2HNO 3 → H 2 SeO 3 + NO + NO 2 H 2 SeO 3 + Na 2 CO 3 → Na 2 SeO 3 + H 2 O + CO 2 Na 2 SeO 3 + H 2 O 2 → Na 2 SeO 4 + H 2 O. It was prepared shortly after the discovery of selenium by Jöns Jacob Berzelius in 1817. Industrial uses Glass manufacturing. One of the earliest applications of sodium selenate was in the glass industry ...
Sodium germanate. [O-] [Ge] (=O) [O-]. [Na+]. [Na+] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Sodium germanate is an inorganic compound with the chemical formula Na 2 GeO 3. It exists as a colorless solid. Sodium germanate is primarily used for the synthesis of other ...
