    摘要： A secure communication session is established between a first device and a second device, by generating, in the first device, a first secret key to be utilized for communication sessions with other devices. The second device requests to establish a first communication session with the first device, and the second device generates a second secret key corresponding to the first secret key of the first device. The second device stores the generated second secret key in a non-volatile memory of the second device, the second secret key being stored in the non-volatile memory in association with an identifier of the first device. Finally, a secure communication session is established between the first and second devices utilizing the first and second secret keys.

    摘要： A device (such as a printer or a network device that may be connected to the printer) that is connected to a network and which performs secure operations using an existing encryption keypair maintained within the device, generates a new encryption keypair within the device by receiving a request from another device on the network to provide an encryption key of the existing encryption keypair to the another device. In response to the request, the device determines whether an encryption key of the existing encryption keypair within the device is valid. In a case where it is determined that the encryption key of the existing encryption keypair is invalid, the device automatically deletes each key of the existing encryption keypair from the device, generates a new encryption keypair within the device and stores the new encryption keypair in the device. The device then provides a new encryption key corresponding to the requested encryption key of the new encryption keypair to another device.

    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： Secure transmission of data to an intended image output device, wherein the data can be used to generate an image at the intended image output device in the presence of an intended recipient. The data is encrypted using a first key. The first key is then encrypted using a second key and a third key. The second key is a public key of a first private key/public key pair, a private key of the first private key/public key pair being primarily in the sole possession of the intended image output device. The third key is a public key of a second private key/public key pair, a private key of the second private key/public key pair being primarily in the sole possession of the intended recipient of the image. The encrypted data and the twice-encrypted first key are transmitted to the intended image output device. The twice-encrypted first key is then decrypted by using the private keys of the second and first key pairs, respectively, which are primarily in the sole possession of the intended recipient device and the intended image output device, respectively. The data is then decrypted and printed at an image output device.

    摘要： Authorized printout of an image corresponding to print data received at a print node from a network. The authorized printout comprises encrypting print data by a print node and storing the encrypted print data without printout, receiving authentication of an intended recipient to print the print data, and decrypting the encrypted print data by the print node and printing the decrypted print data by an image forming device, responsive to receipt of authentication in the receiving step. The print node may be the image forming device itself or a gateway to multiple image forming devices. The print node encrypts the print data with either a symmetric key or an asymmetric key.

    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.
