摘要： A secure Internet Protocol (IP) telephony system, apparatus, and methods are disclosed. Communications over an IP telephony system can be secured by securing communications to and from a Cable Telephony Adapter (CTA). The system can include one or more CTAs, network servers, servers configured as signaling controllers, key distribution centers (KDC), and can include gateways that couple the IP telephony system to a Public Switched Telephone Network (PSTN). Each CTA can be configured as secure hardware and can be configured with multiple encryption keys that are used to communicate signaling or bearer channel communications. The KDC can be configured to periodically distribute symmetric encryption keys to secure communications between devices that have been provisioned to operate in the system and signaling controllers. The secure devices, such as the CTA, can communicate with other secure devices by establishing signaling and bearer channels that are encrypted with session specific symmetric keys derived from a symmetric key distributed by a signaling controller.

摘要： A method is provided for enhancing security of a communication session between first and second endpoints which employs a key management protocol. The method includes sending a first message to a first end point over a communications network requesting a secure communication session therewith. The message includes an identity of a second end point requesting the authenticated communication session. A digital certificate is received from the first endpoint over the communications network. The digital certificate is issued by a certifying source verifying information contained in the digital certificate. The digital certificate includes a plurality of fields, one or more of which are transformed in accordance with a transformation algorithm. A reverse transform is applied to the one or more transformed fields to obtain the one or more fields. The digital certificate is validated and a second message is sent to the first endpoint indicating that validation is complete.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
