# Information About Data Encrypting and Data Encryption Systems

Help! I need to know about data encryption and and several
data encryption  systems. I  also need information as to the
the significance of matrices and how they are used to encode
data.
Thank you very much in advance!

Sincerely yours,
Orifice

As far as data encryption systems, I can't say I know much about them, but data encryption is another matter.

Matrices are used in encryption as coders and de-coders.  First, data in its raw form is translated into a matrix (there are numerous ways to do this; by character, by word, by 10-space block, etc.).  Then a coding matrix is formed, and the two are multiplied together to scramble the data.  When you want to decode the data, you multiply the 'scramble' matrix by the inverse of the coding matrix.  This gives back the original matrix.  My guess is that the encryption system stores the coding matrix and the inverse (more likely just the inverse).

Let me know if you need more than this.

PS:  A 'Matrix Algebra' textbook from a college campus could probably help you with this; that's where I learned what I know.
