Question

Show the matrix representation of the transposition- cipher encryption key with the key (3, 2, 6, 1, 5, 4 ). Find the matrix representation of the decryption key.

Answer 1

Answer:

Encryption Key Matrix:

$$

\begin{bmatrix}

3 & 2 & 6 \\

1 & 5 & 4

\end{bmatrix}

$$

Decryption Key Matrix:

$$

\begin{bmatrix}

3 & 1 \\

2 & 5 \\

6 & 4

\end{bmatrix}

$$

Answer 2

4 2 1 6 5 3 is the Decryption key

A transposition cypher is a cryptographic procedure that creates a cypher text by rearranging the alphabets in the plaintext. The real plain text alphabets are not used in this process.

Example

Columnar transposition cypher, in which each character in the plain text is written horizontally with a specific alphabet width, is a straightforward example of a transposition cypher. When the cypher is written vertically, a completely different cypher text results.

Using the straightforward columnar transposition method, consider the plain text "hello world"

Table Transposition

The cypher text is constructed with a vertical format like holewdlolr using the plain text letters positioned horizontally. The recipient must now decrypt the encryption text to plain text using the same table.
