Back view of people in a meeting, looking at a presentation on a screen. This standard was last reviewed and confirmed in 2016. Therefore this version remains current. IEC 18033-3:2010 specifies block ciphers.
A block cipher is a symmetric encipherment system with the property that the encryption algorithm operates on a block of plaintext, i. 128-bit block ciphers: AES, Camellia, SEED. The encryption algorithm needs to be designed so that the ciphertext yields no information about the plaintext except, perhaps, its length. Associated with every encryption algorithm is a corresponding decryption algorithm, which transforms ciphertext back into its original plaintext.
