Abstract:
Methods and an apparatus for generating random numbers are disclosed. In a first embodiment, a method for generating random numbers involves producing a second random number. A pseudorandom number is produced from a digital random number generator and a first random number is produced from an analog random number generator. The first random number is combined with the pseudorandom number to produce a second random number that is a result of both generators' outputs
Abstract:
A method for updating network-enabled devices with new identity data includes generating a plurality of new identity data records and loading the new identity data records onto an update server. A request is received at the update server for new identity data from at least one network-enabled device having a previously assigned identity linked to an identifier. The previously assigned identifier is linked to a new identifier that is linked to one of the new identity data records. One or more new identity data records are securely delivered to the network-enabled device.
Abstract:
In one embodiment, a method includes receiving a revocation request for revoking a model type of a device. A first computing device determines a list of device unit identifiers (UIDs) that are associated with the model type from a database. The device UIDs are for devices of the model type manufactured by a first entity. The method adds the list of device UIDs to a device revocation list and outputs the device revocation list to revoke a validity of secure information associated with devices associated with the list of device UIDs.
Abstract:
Devices in a telecommunications system are provided with means to self-generate public key pairs and certificates. This eliminates the need for such keys and certificates to be sent to the devices from an outside source so a single-trust approach can be maintained. A manufacturer's certificate is installed into a device it the time of manufacture. The device only issues itself certificates based on a signed request from an external outside server. The device's self-issued certificates incorporate information obtained from the server in a profile. This allows control by the server over a device's self-issued certificates. In order to prevent tampering, and breaking, of the self-issued certificates, the certificate issuing process occurs within a secure microprocessor.
Abstract:
A system and method for securely distributing PKI data, such as one or more private keys or other confidential digital information, from a PKI data generation facility to a product in a product personalization facility that is not connected to the PKI data generation facility and is assumed to be a non-secure product personalization facility. The system includes a PKI data loader for securely transmitting the encrypted PKI data transferred from the PKI data generator to a PKI server at the product personalization facility. The PKI server then transfers the PKI data to the product of interest, typically via a PKI station acting as a proxy between the PKI server and the product. In each communication step, PKI data being transferred is encrypted multiple times and the system is designed such that if any intermediate node is compromised with all of its keys, the overall system has not yet been compromised.

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:
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.
