Abstract: Shannon's equivocation, the conditional entropy of key or message with respect to a specific ciphertext, is the primary indicator of the security of any secrecy system, in that when key equivocation H E (K) or message equivocation H E (M) attain log 0 (or 1) under a brute-force attack, the system is compromised and has no security. We propose a simplistic equivocation definition of security which distinguishes between “secure/unsolvable” and “insecure/solvable” encipherments.

Abstract: A dynamic computer communication security encryption method or system using an initial seed key and multiple random number generators of a specific design, whereby a sequence of independent random entropy values is produced by one set of random number generators and encrypted along with the message stream using the initial seed key, or the output of a second set of random number generators initialized with the initial seed key, and following the subsequent transmission of the variable encrypted entropy/message block, the entropy values are used to symmetrically or identically augment or increase the current uncertainty or entropy of the cryptosystem at both the sender and the receiver, prior to the next encryption block operation.
