In your example, you're using three-digit numbers to represent your alphabet. Are your equations done mod-1000? If not, how do you know which digits make up a single letter? If so, are you aware that A must be relatively prime to 1000 in order for your equation to be reversible? That means you have 400 choices for A. You said you pad with zeros - if we strip the one zero off the end, we have 264 digits, which is 88*3, which doesn't rule out mod-1000 arithmetic. |
