Explanation:
The answer is the Executive-in charge
The concept of an Executive-in charge came from the military’s
chain of command. A chain of command ranges from a supervisor to the top
executive of the organization. When a crisis arises, it is possible that one or
more of the senior top managers may not be available for consultations because
of the travel-intensive positions.
A simple substitution cipher takes each vector (
) and assigns it to the vectors [
] in a one-to-one function so as to make them equivalent.
<h3>What is the Hill cipher?</h3>
In 1929, the Hill cipher was invented by Lester S. Hill and it can be described as a poly-graphic substitution cipher that is typically based on linear algebra and it avails a cryptographer an ability to simultaneously operate on more than three (3) symbols.
In Cryptography, the simple substitution cipher is usually viewed as a function which takes each plaintext letter (alphabet) and assigns it to a ciphertext letter. Thus, it takes each vector (
) and assigns it to the vectors [
] in a one-to-one function so as to make them equivalent.
