calculate the correct digest value. Even if H randomly interferes with the information, as long as the data volume is large, there is little chance of success. For example, using MD5 (a good encryption Digest algorithm invented by RSA), A and B can add 128-bit MAC values to their information. H. I guess the chance of a correct Mac is nearly 1/18, 446,744,073,709,551,616, or about zero. Here is the sample protocol, revised yet again: A-> B HelloB-> A
