Part 3 | Step by Step AES Subbyte Calculation without using S-Box Table | MI | Cryptography

In part 3 of AES subbyte transformation Muliplticative Inverse is computed using Extended Euclidean algorithm. AES is a variant of the Rijndael block cipher[5] developed by two Belgian cryptographers, Joan Daemen and Vincent Rijmen, who submitted a proposal to NIST during the AES selection process.Rijndael is a family of ciphers with different key and block sizes. For AES, NIST selected three members of the Rijndael family, each with a block size of 128 bits, but three different key lengths: 128, 192 and 256 bits.
