1. Simplified DES (S-DES) Key Generation Solved Example in Cryptograhy by Vidya Mahesh Huddar

1. S DES Key Generation Solved Example in Cryptograhy by Vidya Mahesh Huddar

In this video, we learn S-DES Key Generation in Cryptography with a step-by-step solved example.

We start with a 10-bit key (1100011110) and apply the P10 permutation, split the key into two halves, perform Left Shifts (LS-1 and LS-2), and then apply P8 permutation to generate the two subkeys K1 and K2 used in S-DES encryption and decryption.

This video is helpful for students studying:
Cryptography
Information Security
Computer Networks
Cyber Security
VTU / Engineering Exams

Topics covered in this video:
What is S-DES (Simplified Data Encryption Standard)
P10 permutation
Left Shift operations
P8 permutation
Subkey generation (K1 and K2)
Solved numerical example

Watch till the end to clearly understand S-DES key generation for exams and interviews.
