Consider a key generation flowchart for Simplified DES as shown in the figure below: K K 10-bit key 10 15 P10 LS-1 LS-1 P8 5 LS-2 LS-2 P8 Let 10 bit key be 1010111010. Generate the Sub keys K1 and K2 if the Permutation functions(P10 and P8) are defined as below: P10: Input: 1 2 3 4 5 6 7 8 9 10 Output: 3 5 274 10 1986 P8: Input: 1 2 3 4 5678910 Output: 6 3 7 4 8 5 10 9. LS-1: left shift by 1 bit retaining the most significant bits. LS-2 : left shift by 2 bit retaining the most significant bits.
