Iyo Advanced Encryption Standard (AES) mu cryptography, inozivikanwawo seRijndael encryption, chiyero chakatemerwa encryption chakagamuchirwa nehurumende yeUS.
AES mutsauko weRijndael block cipher yakagadziriswa nevaviri veBelgian cryptographer, Joan Daemen naVincent Rijmen, avo vakaendesa chikumbiro kuNIST panguva yesarudzo yeAES. Rijndael seti yemaciphers ane makiyi akasiyana uye saizi yeblock. KuAES, NIST yakasarudza nhengo nhatu dzemhuri yekwaRijndael, imwe neimwe iine block size ye128 bits asi ine makiyi matatu akareba: 128, 192, uye 256 bits.
Iyi chiyero inoshandiswa kutsiva yekutanga DES (Data Encryption Standard) uye yakashandiswa zvakanyanya pasi rese. Mushure memakore mashanu ekusarudza nzira, Advanced Encryption Standard yakaburitswa neNational Institute of Standards and Technology (NIST) muFIPS PUB 197 musi wa26 Mbudzi 2001, uye yakave chiyero chechokwadi musi wa26 Chivabvu 2002. Yepamberi Encryption Standard yakanga yave imwe yeanonyanya kufarirwa algorithms mu symmetric kiyi encryption.
AES inoshandiswa musoftware uye Hardware pasi rese kuti encrypt yakavanzika data. Izvo zvakakosha kune hurumende kuchengetedza komputa, cybersecurity uye zvemagetsi data kuchengetedza.
Zvimiro zveAES (Advanced Encryption Standard):
1.SP Network: Inoshanda pane SP network structure, kwete Feistel cipher structure inoonekwa munyaya yeDES algorithm.
2. Byte Data: Iyo AES encryption algorithm inoshanda pane byte data pane bit data. Saka inobata iyo 128-bit block saizi se16 bytes panguva yekuvharira.
3. Kureba Kwakakosha: Huwandu hwematenderedzwa ekuita zvinoenderana nehurefu hwekiyi inoshandiswa kuvharidzira data. Kune marounds gumi ehukuru hwe10-bit kiyi, 128 rounds ye12-bit key size, uye gumi nemana e192-bit key size.
4. Kuwedzera Kwakakosha: Zvinotora kiyi imwe chete kumusoro panguva yekutanga, iyo inozowedzerwa kune makiyi akawanda anoshandiswa mukutenderera kwega.
Parizvino, mazhinji eFeasycom's Bluetooth modules anotsigira AES-128 encryption data transmission, iyo inovandudza zvakanyanya kuchengetedzwa kwekufambiswa kwedata. Kuti uwane rumwe ruzivo, ndapota taura neFeasycom timu.
