CFB is similar to CBC in that following data is combined with previous data so that identical patterns in the plain text result in different patterns in the cipher text. The difference is that data is encrypted a byte at a time. Each byte is encrypted along with the previous 7 bytes of ciphertext. This mode is useful for data streams, such as terminal sessions, where data arrives a byte at a time. |
