Abstract
To establish credentials, a user network station transmits a first value. An authenticating entity network station generates a first key portion based on the transmitted first value and a second value unknown to the user, splits one of a private key and a public key of a user asymmetric crypto-key into the first key portion and a second key portion, stores the second key portion of the one key so as to be accessible only to the authenticating entity network device, generates a cookie including the second value, transmits the generated cookie to the user network station, and destroys the transmitted first value, the second value, the one key, and the first key portion of the one key. The first value represents a first and the second value included in the transmitted cookie represents a second user credential useable to authenticate the user.
