Cipher Feedback Mode(CFB) | Algorithm Modes in Cryptography
Text to Speech Voices
In this network security video tutorial we will study and understand the working of Cipher Cipher Feedback (CFB) also known as CFB algorithm mode.
Cipher Feedback (CFB) -
1. In this mode data is encrypted in units that are smaller (e.g. they could be of size 8 bits) than a defined block size (which is usually 64 bits).
2. CFB mode works with j bits at a time (as we have seen, usually, but not always , j = 8)
Following are the steps of CFB mode -
Step 1 - Encrypt the IV(initialization vector) using the KEY to get the Encrypted IV.
Step 2 - Perform XOR operation between first j bits of encrypted IV and j bits of Plain Text to get j bits of Cipher Text(Cipher text block 1)
Step 3 - left shift the IV by j bits & add the cipher text block from the previous step to the right most side of the IV.
