Abstract
A first network station encrypts a first message with a first key portion from a first split of a private or public key of a user's asymmetric crypto-key and transmits it during a network session. The second network station decrypts the transmitted encrypted first message with a second key portion from the first split of the one key of the asymmetric crypto-key to initially authenticate the user for access, during the session, to store information. The first network station also encrypts a second message with another first key portion from a second split of that one key, and subsequently transmits it during the same network session. The second network station decrypts the subsequently transmitted encrypted second message with another second key portion from the second split of that same one key to subsequently authenticate the user for access, during the same session, to other stored_information.
