    摘要: Access control to a networked peripheral device by a walk-up user, wherein the networked peripheral device is accessible by both the walk-up user and a remote user, based on centralized access management information. Access control comprises receiving authenticated information for the walk-up user from the networked peripheral device at a centralized location, determining at a server connected to the network a first level of access to the networked peripheral device, determining at the networked peripheral device a second level of access to the networked peripheral device by the walk-up user based on received access management information for the walk-up user, and allowing the walk-up user to access determined user-available features of the networked peripheral device based on the determined first and second levels of access.

    摘要: The invention provides for installing encryption keys on a device not having any previous security credentials. An installation authority generates a security token to be used by the device for secure communications, and an installation credential for the device, and stores them in association with one another. A user of the device is provided with the installation credential, whereby the user inputs the installation credential into the device. The device utilizes the installation credential as a temporary security key, establishes a secure communication channel with the installation authority and requests provision of the security token. The installation authority provides the security token associated with the installation credential to the device over the established secure communication channel, and the device installs the security token, after which the device erases the installation credential from the device. The installation authority may also certify the security token and provide a certified token and a root verification certificate to the device.

    摘要: Obtaining exclusive control of a printing device by deferring printing of print data in a print queue. To obtain control, the recipient performs a process which may include authentication of the recipient. Control may be obtained either before the recipient is authenticated or after a successful authentication process. After the recipient has obtained control, print data in the print queue is temporarily deferred from being printed. The recipient may then select a print job to print, including selecting a print job from among the print jobs deferred in the print queue, or selecting a file to print over a network, including the Internet or an intranet. Further, printing device resources utilized in printing data during the period of exclusive control may be tracked and correlated to the recipient who has control.

    摘要: An interface modem for use in a broadband local area data network with collision avoidance protocol. The data link controller features hardware acknowledge circuitry that acknowledges the receipt of a perfect data packet immediately upon receipt thereof without request to or assistance by the client data processing unit. The DLC prepares the acknowledgement packet from the incoming data packet and places it on the data link without going through a line acquisition protocol. Each received acknowledgment packet is placed in a transmit buffer at a known location relative to the data packet which was just transmitted, for which it is an acknowledgment so that each acknowledgment packet may be located in less time by the client data processing unit. The acknowledgment packets are logically part of the transmit process and are therefore placed in the transmit buffer.
