20090006852Method and Apparatus for Securing Unlock Password Generation and Distribution - A process may be utilized for securing unlock password generation and distribution. A first set of exclusive responsibilities, assigned to a trusted authority, includes random generation and encryption of an unlock password to compose a randomly generated encrypted unlock password. Further, a second set of exclusive responsibilities, assigned to a security agent, includes sending information associated with the unlock password and a digital signature of information associated with the unlock password to a communication device configured for a network in order to mate the unlock password to the communication device, and sending the randomly generated and encrypted unlock password along with mating data to a password processing center. In addition, a third set of exclusive responsibilities, assigned to a password processing center, includes decrypting the randomly generated and encrypted unlock password.01-01-2009
20090031131Token-Based Management System for PKI Personalization Process - A system for token-based management of a PKI personalization process includes a token request and management system (TRMS) configured to gather request information from a requestor; and a token personalization system (TPS) configured to personalize a hardware token such that usage of the hardware token is constrained by the request information. A method for token-based management of a PKI personalization process includes: requesting a hardware token; personalizing a hardware token such that the hardware token is confined to operation within limiting parameters; binding the hardware token to a workstation which is configured receive the hardware token and use credentials within the hardware token to request and download PKI data from a PKI server, the workstation being further configured to personalize an end user product by loading the PKI data into internal memory contained within the end user product; and monitoring usage of the hardware token and the PKI data.01-29-2009
20090037931Method and Apparatus for a Dynamic and Real-Time Configurable Software Architecture for Manufacturing Personalization - A process receives a personalization request to personalize a communication device. Further, the process provides the personalization request to a message controller that composes a message having personalization information with a message composer engine according to a set of rules and configures one or more communication parameters for the message with a message flow control engine according to the set of rules. The set of rules indicates a distributed environment set of files that the message composer engine and the message flow control engine utilize in a distributed environment, and a centralized environment set of files that the message composer engine and the message flow control engine utilize in a centralized environment.02-05-2009
20110047374METHOD AND APPARATUS FOR A CONFIGURABLE ONLINE PUBLIC KEY INFRASTRUCTURE (PKI) MANAGEMENT SYSTEM - A method and apparatus are provided for generating identity data to be provisioned in product devices that are a part of a project. The method includes establishing a template associated with each CA in a hierarchical chain of CAs having a root CA at a highest level in the chain and a signing CA at a lowest level in the chain. The template associated with the signing CA inherits mandatory attribute fields specified in the root CA and any intermediate CA in the hierarchical chain. The mandatory attribute fields are user-specifiable fields to be populated with PKI data. A configuration file is generated upon receipt of an order for digital certificates using PKI data provided by a user to populate the mandatory attribute fields of the template associated with the signing CA. The digital certificates requested in the order are generated using the PKI data in the configuration file.02-24-2011
20110197061CONFIGURABLE ONLINE PUBLIC KEY INFRASTRUCTURE (PKI) MANAGEMENT FRAMEWORK - A method and apparatus is provided for establishing a process for provisioning a digital certificate service delivered by a PKI system. The method includes receiving a request for a digital certificate service and receiving data specifying a project that includes at least one product to be provisioned with a digital certificate. Data specifying an identification of an owner organization of the project and at least one participant organization participating in the project is also received. Attributes with which PKI data to be included in the digital certificates is to comply is received from the owner organization. Based on the received data and attributes, an account is established for each of the organizations associated with the project through which users associated with each of the organizations can respectively request digital certificates for the at least one product in accordance with the attributes received from the owner organization.08-11-2011

20090321456OBJECT STORAGE DEVICE - An object storage device that includes a base and a deformable body having a bottom surface fixed to the base is provided. The body also includes body end surfaces, a longitudinal axis, a transverse axis extending between the body end surfaces, and a plurality of fingers. Each of the fingers includes an upper portion opposite the bottom surface, the upper portion including at least one planar diagonally extending surface configured to guide an object. Each of the fingers also includes finger side surfaces, and the finger side surfaces of adjacent fingers are frictionally engaged. With this construction, the object storage device may hold an object in place by friction forces due to contact between the sides of the object and the finger side surfaces. As such, the possibility of piercing the device with a sharp part of an object may be reduced.12-31-2009

20090323705METHOD FOR IMPLEMENTING PHOTOELECTRIC MUTEX, ETHERNET PHOTOELECTRIC MUTEX INTERFACE DEVICE AND NETWORK EQUIPMENT - A method for implementing photoelectric mutex, an Ethernet photoelectric mutex interface device, and network equipment are provided. The Ethernet photoelectric mutex interface device includes a channel switching module, a first Ethernet physical layer (PHY) chip, and a second Ethernet PHY chip. The channel switching module is connected to the first Ethernet PHY chip through a first interface and connected to the second Ethernet PHY chip through a second interface respectively, and is adapted to perform data transmission through the first Ethernet PHY chip and when a presence signal of an optical interface data transmission module is detected, perform data transmission through the second Ethernet PHY chip. Thus, a cost of equipment for implementing a photoelectric mutex function in an Ethernet is reduced, and a utilization rate of transmission resources is improved.12-31-2009
