There r lots of predefined tables in DES like PC-1, PC-2, IP etc.Could you pls explain how these tables are created and what basis.
Really, I don't know. Thank you for asking. I will find the answer.
Share this video with others and subscribe my channel.
I don't know the answer to the question, how this tables are created. But why it is created is relatively straight forward answer. It is to increase the diffusion in data. So that an attacker can't differentiate between an encrypted text and random garbage. I don't know, whether that was part of your question, but I answered anyway.

we use the same sbox to all 8parts of 6bits key to convert it into 8parts of 4bits key??
Because in starting key value is 56 (coz 8 bit was discarded in 1st round) and plain text size in 64 bits. So both are divided in two halves... So, I have to 8 parts of 4 bits key
15:34 How to know which s box to use there are 8 s-boxes?
It is already defined by the scientist who was innovate this DES algorithm.
why do we take till 16th rounds only. Thank you for the video.
Because DES algorithm uses the Feistel cipher structure... Feistel cipher uses 16 rounds of encryption.
