1. What is one problem with the substitution cipher?

Shown in the video, it is noticeable that this encryption
method was flawed because of how it was solvable using the frequency analysis.
Frequency analysis is when you find a common letter used in the English
alphabet such as ‘e’ and by finding another letter that is just as common and
using that code scheme to work out the whole message.

2.What is one way to overcome this problem?

A way that we could solve this problem is by not only
encrypting the message 1 way but multiple. For example we could make the
message translated into several other languages that use the same shapes as the
letters in the English alphabet such as French or German then  that way the message will have another
process that it must be solved before readable.
