Advanced Encryption Standard (AES) mu cryptography, yomwe imadziwikanso kuti Rijndael encryption, ndi mulingo wachinsinsi womwe boma la US lidatengera.
AES ndi mtundu wina wa Rijndael block cipher wopangidwa ndi olemba mbiri aku Belgian, Joan Daemen ndi Vincent Rijmen, omwe adapereka lingaliro ku NIST panthawi yosankha AES. Rijndael ndi seti ya ma ciphers okhala ndi makiyi osiyanasiyana ndi makulidwe a block. Kwa AES, NIST inasankha anthu atatu a m'banja la Rijndael, aliyense ali ndi 128 bits kukula kwake koma ndi mautali atatu osiyana: 128, 192, ndi 256 bits.
Mulingo uwu umagwiritsidwa ntchito m'malo mwa DES (Data Encryption Standard) ndipo wakhala ukugwiritsidwa ntchito padziko lonse lapansi. Pambuyo pa zaka zisanu zosankhidwa, Advanced Encryption Standard inasindikizidwa ndi National Institute of Standards and Technology (NIST) mu FIPS PUB 197 pa November 26, 2001, ndipo inakhala muyeso wovomerezeka pa May 26, 2002. Advanced Encryption Standard idakhala imodzi mwama algorithms odziwika bwino pakubisa makiyi a symmetric.
AES ikugwiritsidwa ntchito mu mapulogalamu ndi ma hardware padziko lonse lapansi kuti asungire deta yovuta. Ndikofunikira pachitetezo cha makompyuta aboma, chitetezo cha pa intaneti komanso chitetezo cha data pakompyuta.
Mawonekedwe a AES (Advanced Encryption Standard):
1.SP Network: Imagwira ntchito pa SP network structure, osati Feistel cipher structure yomwe ikuwoneka pa nkhani ya DES algorithm.
2. Byte Data: AES encryption algorithm imagwira ntchito pa data ya byte m'malo mwa bit data. Chifukwa chake imagwira kukula kwa chipika cha 128-bit ngati ma byte 16 pakubisa.
3. Utali Wautali: Kuchuluka kwa maulendo oti mupereke kumadalira kutalika kwa kiyi yomwe imagwiritsidwa ntchito kubisa deta. Pali zozungulira 10 za 128-bit key size, 12 round for 192-bit key size, and 14 round to 256-bit key size.
4. Kukulitsa Mfungulo: Zimatengera kiyi imodzi mmwamba pa gawo loyamba, lomwe pambuyo pake limakulitsidwa kukhala makiyi angapo omwe amagwiritsidwa ntchito pozungulira pawokha.
Pakalipano, ma modules ambiri a Feasycom a Bluetooth amathandizira kutumiza kwa deta ya AES-128, yomwe imathandizira kwambiri chitetezo cha kufalitsa deta. Kuti mudziwe zambiri, chonde lemberani gulu la Feasycom.
