To encrypt the message 'Buy twenty million' using a tabular transposition cipher with the encryption keyword 'RENTans', divide the message into blocks, arrange the blocks in alphabetical order according to the keyword, and read the letters row by row to obtain the encrypted message.
To encrypt the message 'Buy twenty million' using a tabular transposition cipher with the encryption keyword 'RENTans', follow these steps:
Separate the message into blocks of equal length based on the keyword length. In this case, the keyword 'RENTans' has a length of 8, so divide the message into blocks of 8 letters: 'Buy twent', 'y million'.
Arrange the blocks in alphabetical order according to the keyword. In this case, the blocks will be arranged as 'y million', 'Buy twent'.
Read the letters in the rearranged blocks row by row. The encrypted message will be 'y miltonwBuy enet'.
Therefore, the encrypted message for 'Buy twenty million' using the tabular transposition cipher with the encryption keyword 'RENTans' is 'y miltonwBuy enet'.
The probable question may be:
Encrypt the message "Buy twenty million" using a tabular transposition cipher with the encryption keyword "RENT".
