O le Advanced Encryption Standard (AES) i cryptography, e taʻua foi o Rijndael encryption, o se faʻamatalaga faʻamalamalamaga tulaga faʻaogaina e le malo tele o Amerika.
O le AES o se fesuiaiga o le Rijndael block cipher na atiaʻe e ni tagata e toʻalua Belgian cryptographers, Joan Daemen ma Vincent Rijmen, oe na tuʻuina atu se talosaga i le NIST i le faagasologa o le filifiliga AES. Rijndael o se seti o ciphers ma ki eseese ma poloka tetele. Mo AES, na filifilia e le NIST sui e toatolu o le aiga o Rijndael, e tofu le tasi ma le poloka poloka o 128 bits ae tolu umi ki eseese: 128, 192, ma le 256 bits.
O lenei tulaga e faʻaaogaina e sui ai le DES (Data Encryption Standard) ma ua faʻaaogaina lautele i le lalolagi atoa. Ina ua maeʻa le lima tausaga o filifiliga, na lomia le Advanced Encryption Standard e le National Institute of Standards and Technology (NIST) i FIPS PUB 197 i le aso 26 o Novema, 2001, ma avea ma tulaga faʻamaonia i le aso 26 o Me, 2002. I le 2006, le Advanced Encryption Standard ua avea ma se tasi o algorithms sili ona lauiloa i faʻailoga ki faʻamaufaʻailoga.
O lo'o fa'atinoina le AES i polokalama fa'akomepiuta ma masini i le lalolagi atoa e fa'ailoga ai fa'amatalaga ma'ale'ale. E taua mo le puipuiga o komepiuta a le malo, saogalemu i luga ole laiga ma le puipuiga o faamatalaga faaeletonika.
Vaega o le AES (Advanced Encryption Standard):
1.SP Network: E galue i luga o le fausaga fesoʻotaʻiga SP, ae le o le Feistel cipher structure o loʻo vaʻaia i le tulaga o le DES algorithm.
2. Byte Data: O le AES encryption algorithm e galue i luga o faʻamatalaga byte nai lo faʻamatalaga bit. O lea e togafitia ai le 128-bit poloka tetele e pei o le 16 bytes i le taimi o faʻamatalaga.
3. Umi ole Ki: Ole numera o ta'amilosaga e fa'atino e fa'atatau ile umi ole ki e fa'aoga e fa'ailoga ai fa'amaumauga. E 10 ta'amilosaga mo le 128-bit lapopo'a ki, 12 ta'amilosaga mo le 192-bit ki tele, ma le 14 ta'amilosaga mo le 256-bit lapo'a ki.
4. Fa'alauteleina Ki: E mana'omia se ki se tasi i luga i le taimi muamua, lea e fa'alautele mulimuli ane i le tele o ki fa'aaoga i ta'amilosaga ta'itasi.
I le taimi nei, o le tele o Feasycom's Bluetooth modules e lagolagoina AES-128 faʻamatalaga faʻamatalaga faʻamatalaga, lea e faʻaleleia atili ai le saogalemu o faʻamatalaga faʻamatalaga. Mo nisi fa'amatalaga, fa'amolemole fa'afeso'ota'i le 'au a Feasycom.
