I am continuing my practice on problems for my cryptography class. I'm starting to get the hang of basic ideas of ciphers. At least i thought this until I attempted to do the follwng problem:
The encryption key in a transposition cipher is
$(5, 12, 3, 7, 9, 6, 4, 14, 1, 13, 10 , 8, 15, 2, 11,16)$.
Find the decryption key
I'm not even sure where or how to begin this problem. I've looked online to see if i came across any problems similar to this, but i have not found anything like this. Any help in pushing me in the right direction towards solving this would be greatly appreciated. Thanks!
Most of the stuff i've found involves words unlike this one.
