CONCEPTION

Advanced Encryption Standard (AES), a subset of the Rijndael cipher, which is a symmetric-key algorithm, meaning the same key is used for both encrypting and decrypting the data.

Block Cipher Mode of Operation

• ECB - Same cipher text with same plain text. No use of IV.

• CBC - Different cipher text with same plain text. Using IV. (The most commonly used mode of operation)
