Question

Hello,

My name is Cierra and I'm a bit nervous on where I need to start to complete my assignment.

I would appreciate some tips on what formula's to use and what direction I should take to answer a few questions.

I want to have a better understanding of what questions I am getting myself into.

Thank you.

Cryptography: What does this coded message say??

Matrix inverses can provide a simple and effective procedure for encoding and decoding messages.

40 58 37 51 11 11 43 58 28 33 30 45 24 25 52 72 37 51 5 5

[A] = encoder [B] = uncoded [C] = coded and [A][B] = [C]

Since the encoding matrix, A, is 2x2, create matrix C with two rows. Go down the columns, not across the rows. i.e.

e_{11} = 40 e_{21} = 58 e_{12} = 37
etc.

[A] = [1 2]

[1 3]

[C] = [ _ _ _ _ _ _ _ _ _ _ ]

[ _ _ _ _ _ _ _ _ _ _ ]

Now, solve for matrix B.

[B] = [ _ _ _ _ _ _ _ _ _ _ ]

[ _ _ _ _ _ _ _ _ _ _ ]

List the elements in the columns of matrix B in sequence.

__ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __ __

Assign the numbers 1-26 to the letters of the alphabet with A=1, B=2, C=3, etc and BLANK =0
