Hello,

I've written a Delphi-program to encode textmessages with

matrix-multiplication. The decoding-matrix is the inverse matrix of the

encoding-matrix. You can choose a n-dimensional matrix.

Now I'm wondering how secure this method is. How can I translate the

"security" in bits (like "128 bits")?

I have designed this program in our computer science lesson and my

teacher want to know the security especially compared with standards

like DES etc.

I hope that somebody can help me!

Thanks, Anton
