Cipher Block Chaining (CBC)

[@KawtherBenElkahia-gz5sk]

I skipped my IT Security lectures, but his videos have rescued me ! Keep the good work

Bro you're like the best teacher ever

[@leehaynes7761]

Thank you for creating this video, you have really helped me understand in a clear way how CBC works.

[@NanthaGopalJ-o6r]

you are explaining better than my professor,

[@josemorris1790]

Very good explanation

[@jagadeshn4730]

Nice explanation !!

[@heyiamuday]

wow ../ great explanation

[@robertkrasniqi6612]

Thank you for the video, it is very helpful! At 6:43, why does CBC also offer authentication, you justify it with the IV, but this is not transmitted securely?

i studied my all engineering courses on this platform and now I m worried that their are no lecture available on communication system

[@souravbhagat1358]

Pls make a vedio lectures on Internet security protocol which is tha part of network security and also authentication part

[@fadalinitube]

Thank u so much

I hope you will reply, i have a question, is the encryption part then something like AES Encryption? So for the first block of the plaintext we are combining it the IV via XOR and this output will be get to AES for encryption and so on?

[@mertcanzafer9901]

There is also one thing I noticed here is that even if we can not encrypt the data in parallel, but we can decrypt the data in parallel using CBC operation. How? Because all ciphertext are known so you don't need to wait for previous ciphertext to produce the plain text!!!

nice!

how the IV is extracted during the decryption?

[@1004-u5t]

but both sides need to know rhe key as well so the key provides authentication for all modes.
