    摘要： Methods and an apparatus for storing information in a processing device with flexible security are disclosed. In one embodiment, a method stores information within the processing device. The method receives a download via a first input path which includes a first breakable link and stores the download within the processing device. At some point, a key is also stored within the processing device. A ciphertext download is received via a second input path which includes a second breakable link. The ciphertext download is decrypted utilizing the key and the resulting plaintext download is stored within the processing device.

    摘要： A system is described for uniquely mating components of a communication network such as a smartcard and a set-top box. When mated, the smartcard and set-top box are tied together and have a single identity. Further, the smartcard operates properly only when inserted into an authorized set-top box. Exchanges of information between both components are secured by encryption and authentication to guard against piracy of the exchanged information. The system provides the same authentication key to the set-top box and the smartcard. This key is used for authenticating communication between the set-top box and the smartcard. First, the authentication key is encrypted by a set-top box mating key. The set-top box employs this mating key to decrypt the authentication key. After it is derived, the authentication key is stored in the set-top box's memory. Further, the same authentication key is encrypted by a smartcard mating key. Thereafter, the smartcard employs the smartcard mating key to extract the authentication key. The clear authentication key is stored in the smartcard's memory as well. In this manner, the authentication key is used for securing all communication between the set-top box and the smart-card. For example, the set-top box may request control words from the smartcard. Only after authenticating the request, are the control words for decrypting digital content provided to the set-top box. If the smartcard authentication key is different from the set-top box key, the request for control words is denied.

    摘要： The present invention discloses a system and method for providing a secured system time reference to a subscriber device, e.g., a set top box or a receiver. In one embodiment, the system time reference is provided in a secure system time message that is broadcasted to a plurality of subscriber devices. Each subscriber device has a security device or software application that is capable of determining whether the received system time reference is legitimate. If the system time reference is determined to be legitimate, a local time reference is synchronized with said received system time reference.

    摘要： Multiple public/private key pairs of varying levels of security are used to provide a high level of security while still allowing fast processing of encrypted information. The lower-security level includes keys that are small in length, that are changed relatively often, and that require less or fewer resources to implement their functions. When it is required to change key pairs of low security, a key pair at a higher security level (i.e., longer length keys) than the lower-security level keys is used to transfer the new lower-security public keys to devices using those keys. The higher-security keys can, in turn, be changed at a frequency lower than the lower-security keys. The higher-security keys require a higher level of resources to perform their coding operations. This approach of using keys of escalating levels of security to replace lower-security keys, where the higher-security keys require more resources, are more secure, and are replaced less often than the lower-security keys, can be followed as many times as is desired to create a hierarchy of public key uses with the result that the lower-security operations can be performed quickly while the overall system security is high.

    摘要： 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.

    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.
