Abstract:
An apparatus and method for providing at least one root certificate are disclosed. Specifically, a plurality of root certificates is received and stored. Afterwards, a request is received from a first endpoint device for a desired root certificate, where the desired root certificate is used by the first endpoint device to verify an identity of a second endpoint device. Furthermore, the first endpoint device and the second endpoint device are associated with different certificate hierarchies. The desired root certificate is then sent to at least the first endpoint device.
Abstract:
According to one embodiment of the invention a system is utilized to leverage the security arrangement between a first and second device to establish a secure link between the first device and a third device. One embodiment of the invention is particularly suitable for loading security data on a set top box, such as that utilized in the cable television industry.
Abstract:
A system using digital certificates having overlapping validity intervals. The overlapping certificates can be used in a hierarchical certificate authorities network in order to obtain benefits such as to increase the usage of all the certificates in the certificate chain; reduce/eliminate the certificate updates/downloads to a large population; only replace the minimum number of certificates in the trust hierarchy to re-establish the certificate chain; reduce the complexity of maintaining certificate nesting in certificate generation process; reduce the risk of service interruption; and control the extent of older technology in circulation and to reduce the risk associated with older products being more susceptible to attack. The certificate renewal process of a preferred embodiment is described.
Abstract:
A system to change security levels is used to change the level of security used in a secured processing system. The system uses a status indicator to designate the security level being implemented. The security level can be upgraded to allow a higher level of security to be implemented with relative ease. However, in order to change from a higher level of security to a lower level of security, an authorization code is utilized to confirm that the change in security is authorized.
Abstract:
A high-strength, high-toughness, weldable and deformable rare earth magnesium alloy comprised of 0.7˜1.7% of Ym, 5.5˜6.4% of Zn, 0.45˜0.8% of Zr, 0.02% or less of the total amount of impurity elements of Si, Fe, Cu and Ni, and the remainder of Mg, based on the total weight of the alloy. During smelting, Y, Ho, Er, Gd and Zr are added in a manner of Mg—Y-rich, Mg—Zr intermediate alloys into a magnesium melt; Zn is added in a manner of pure Zn, and at 690˜720° C., a round bar was cast by a semi-continuous casting or a water cooled mould, then an extrusion molding was performed at 380˜410° C. after cutting. Before the extrusion, the alloy is treated by the solid-solution treatment at 480˜510° C. for 2˜3 hours, however, the alloy can also be extrusion molded directly without the solid-solution treatment. After the extrusion molding, this alloy has a strength of 340 MPa or more and a percentage elongation of 14% or more at room temperature and is a high-strength, high-toughness, weldable and deformable rare earth magnesium alloy.
Abstract:
A system to transmit a set of programs from a transmitter to a receiver is used to accommodate different levels of security used for each program. When a high level of security is necessary for transmitting or receiving a program the transmitter and/or receiver is operable to accommodate that level of security. Thus, both transmitters and receivers are operable to be reconfigured to encrypt or decrypt, respectively, at different levels. Accordingly, differing amounts of programs can be transmitted or received based on the resource requirements needed at any level of security. Consequently, a high level of encryption/decryption requires more resources and allows the processing of fewer services, while a lower level of encryption/decryption allows more services to be transmitted/received.
Abstract:
A method is provided for securely delivering identity data units over a communications network to a client device. The method includes receiving a selection from a customer identifying a final zipped package to be unpacked. The final zipped package is unpacked to obtain a common package and a digital signature file signed by an entity generating identity data requested by the customer. The digital signature in the digital signature file is verified and the common package is unpacked to obtain a plurality of outer packages and an encrypted symmetric key. The symmetric key is decrypted with a private key associated with the customer and each of the outer packages is decrypted with the symmetric key to obtain a plurality of identity data units.
Abstract:
A method and apparatus is provided for maintaining inventory levels of identity data to be provisioned in electronic devices. The method includes monitoring over a communications network inventory levels of identity data records stored on a plurality of identity data personalization servers that each provision electronic devices with an identity data record. Additionally, if the inventory level on at least one of the identity data personalization servers falls below a minimum specified level, a refill request is sent to an identity data management authority requesting that additional identity data records be uploaded to the identity data personalization server.
Abstract:
A system for token-based management of a PKI (public key infrastructure) 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.
