摘要:
A system for managing cryptographic keys and trust relationships in a secure shell (SSH) environment by mapping network servers, clients, and appliances and locating SSH keys and key pairs associated with each device. The system provides for mapping the network topology and all SSH keys and key pairs stored on network connected devices, and the creation of a master database of all devices, keys and key pairs, key types and encryption strength, and user accounts with which each key or key pair is associated. The mapping and database enable the effective management of SSH keys and key pairs, detection of errors and weakness, elimination of orphaned or outdated keys, correction of all deficiencies, and replacement of keys in accordance with policies set by the organization maintaining the network.
摘要:
An improved immersible oxygen probe for molten metals has a gas permeable body including an immersion end and a support end adapted for being supported by a lance. An oxygen cell and a thermocouple are supported in the immersion end of the body. An unobstructed gas flow passageway is provided through the gas permeable bodies and through the probe body from the immersion end to the support/connector end whereby gases released from the molten metal and sensor body during immersion readily pass through the probe and can escape from within the probe. Thus rapid analysis of the molten metal with improved accuracy within a few seconds after immersion is achieved.

Apparatus is provided for measurement and display of at least one characteristic of molten metal contained in a metal processing vessel that includes a probe supported by an immersion end of a lance. The probe is adapted to be submerged in the molten metal to obtain data in analog form identifying at least one characteristic of the metal while a module is connected to an end of the lance opposite from the immersion end. The module contains electronic circuitry for receiving analog data and for converting the analog data into digital form, and the module also contains electronic circuitry for transmitting digital data to a remotely located receiving device which may be a microprocessor used in readout and control of the metallurgical process.

A method of managing reliance in an electronic transaction system includes a certification authority issuing a primary certificate to a subscriber and forwarding to a reliance server, information about the issued primary certificate. The reliance server maintains the forwarded information about issued primary certificate. The subscriber forms a transaction and then provides the transaction to a relying party. The transaction includes the primary certificate or a reference thereto. The relying party sends to the reliance server a request for assurance based on the transaction received from the subscriber. The reliance server determines whether to provide the requested assurance based on the information about the issued primary certificate and on the requested assurance. Based on the determining, the reliance server issues to the relying party a secondary certificate providing the assurance to the relying party.
