Abstract
A system for authenticating communication network users includes a user-associated user station communicatively coupled to an authenticating station via the communication network. The authenticating station is configured to authenticate the user and receive a first value, representing a first user credential, from the user station. A first key portion is generated based on the first value and a second value that is unknown to the user. The first key portion, along with a second key portion, is used for authenticating credentials of the user for a predefined period of time or for authenticating user credentials for a predefined number of times. The second key portion is generated based on the first key portion. A cookie that includes the second value or a value derived from the second value is generated and transmitted to the user station and then the second value is destroyed.
