A system and method for preventing interception and decryption of
information by an unauthorized party when that information is transmitted
over a network is provided. A token is used to encrypt one-time password
that is different for each network session, to prevent decryption
thereof. The encrypted one-time password is returned to a network server
for authentication by the server. The network server generates its
response in a similar fashion. The server compares its response to the
one-time password, to determine if they match. If they match, then the
client is granted access to the network. If they responses do not match,
then the client is denied access to the network by the server.
