Use S$-$DES algorithm to encrypt the following message:

K$=1010110110$

Plaintext is $00010011$

by following these steps :

$1.$ Initial Permutation $($IP$)$: Permute the plaintext according to the initial permutation table.

$2.$ Splitting and Expanding: Split the permuted plaintext into two halves, left $($L$0)$ and right $($R$0),$ each $4$ bits long. Expand R$0$ to $8$ bits using the expansion function.

$3.$ Key Generation: Generate the subkeys K$1$ and K$2$ from the given key K$.$

$4.$ Round $1$:

$-$ Expansion: Expand R$0$ to $8$ bits.

$-$ XOR with Key: XOR the expanded R$0$ with K$1.$

$-$ Substitution: Perform substitution using the S$-$boxes.

$-$ Permutation: Permute the result.

$-$ XOR with L$0$: XOR the permuted result with L$0.$

$-$ Round $2$:

$-$ Repeat the steps above using K$2$ instead of K$1.$

$5.$ Final Permutation $($IP$-1)$: Permute the concatenation of the final L and R halves to get the ciphertext.

By following these steps, you can encrypt the plaintext $"00010011"$ using the S$-$DES algorithm with the provided key.
