Answer:
Encrypted message: CPONYIERTN
Explanation:
Message = ENCRYPTION
keyword = ONE
keyword ONE is of length 3 so the rows are of length 3
Permutation is given by the alphabetical order of the letters in the keyword ONE. Here E appears first in alphabet, then comes N and in last comes O so the order would be 321.
Now the message ENCRYPTION is written in tabular form with width of the rows defined by a keyword ONE
O N E
3 2 1
E N C
R Y P
T I O
N
Now this message is read by the column in alphabetic order of the keyword ONE.
Since alphabetic order of E is 1 so the column under E is read first which has the letters:
CPO
Then column under N is read which has the letters:
NYI
In the last the column under O is read which has the letters:
ERTN
So the encrypted message is:
CPONYIERTN
