A Practical Infinite 1timepad Cypher Messaging System!
Posted:

Using irrational numbers for cypher pads is not new however calculation of the nTH digit of pi, sqrt(2) etc.
at the
123456789012345678901234567890TH digit
assuming 30 digit numbers are hard to guess with brute force...
is too intensive in calculations to be effective.

What's needed is a FAST irrational non repeating pattern of digits calculation algorithm, such as:
CHAMPERNOWNE'S CONSTANT
0.1234567891011121314....
At first it seems quite useless for a cypher as the digit blocks repeat one after another with only the final digit regularly changing.
e.g. at the MILLIONTH DIGIT POSITION
...5555556555555755555585555559555....
which is not much better than a repeating 7 digit string of digits.

However all that's needed is a LOOKUP SYSTEM where the digit position is hidden from intermediate communication nodes so only the SENDER and RECEIVER know which digit position of C.C. to lookup and see what the number>>letter is!
e.g.
SECRET CYPHER: 11111222223333344444 (20 digits long)
MESSAGE: H E L L O
LETTER = 'H' (8) REPEAT:
i = rand(100000000000000000000, 99999999999999999999)
UNTIL CC[ CYPHER+i ]*10 + CC[CYPHER+i+1] = LETTER
WRITE CC[ CYPHER+i ]*10 + CC[CYPHER+i+1]
This is a RANDOM ACCESS CYPHER approach where the N.S.A. has NO FURKEN CLUE what your talking 'bout Yo!
