Kevin, a security team member, was instructed to share a policy document with the employees. As it was supposed to be shared within the network, he…

A transposition cipher is a type of cipher that encrypts a document by rearranging the same

characters to produce the ciphertext. A transposition cipher does not change the identity or

frequency of the characters, but only their position. A transposition cipher can use various methods

to permute the characters, such as writing them in a grid and reading them in a different order, or

shifting them along a rail fence pattern. A transposition cipher is a simple and fast algorithm, but it

can be easily broken by frequency analysis or anagramming. A transposition cipher is the type of

cipher employed by Kevin in the above scenario, as he used a simple algorithm to encrypt the

document that just rearranges the same characters to produce the ciphertext. Reference:
