A method and system for continuously serving the authentication requests of networked computers is disclosed. The authentication requests of computers are served and the services for the computers are reserved for a predefined time interval. The authentication service for a computer is reserved by an authentication server, which receives authentication requests of the computer.

Method and system for continuously serving authentication requests

Automatically re-authenticating a computing device seeking access to a network or a resource. A method comprises forwarding a request received from the computing device to an authentication device to enable the authentication device to authenticate the computing device using a full-authentication mechanism. State information related to authenticating the computing device is created from authenticating the computing device. The state information is received and stored. For example, an authenticator device that forwarded the initial authentication request from the computing device to the authentication device receives and stores the state information. The computing device is re-authenticated using the stored state information without again contacting the authentication device.

Verifying revocation status of a digital certificate is provided in part by a receiver verifying a security certificate for a sender. In an embodiment, an approach comprises receiving a first security certificate associated with the sender and storing the security certificate in a location accessible to the receiver; updating the first security certificate in the location accessible to the receiver if the first security certificate is changed or revoked; receiving a second security certificate from the sender when identity of the sender needs to be verified; comparing the second security certificate to the first security certificate; and confirming the sender's identity only if the second security certificate matches the first security certificate for the sender.

Method and apparatus for verifying revocation status of a digital certificate

A method and apparatus for verifying revocation status of a digital certificate is provided. The invention operates in part by a receiver verifying a security certificate for a sender. In various embodiments the steps to accomplish this include receiving a first security certificate associated with the sender and storing the security certificate in a location accessible to the receiver; updating the first security certificate in the location accessible to the receiver if the first security certificate is changed or revoked; receiving a second security certificate from the sender when identity of the sender needs to be verified; comparing the second security certificate to the first security certificate; and confirming the sender's identity only if the second security certificate matches the first security certificate for the sender.
