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.

摘要： A system is described for allowing “pay by time” purchasing of digital video programming. The system provides for a variable or metered approach. A user can purchase a fraction of a program for a price different from that required for purchasing the entire program. Records of the user's viewing can be created to record, e.g., when a user started receiving a program, how long the user received a program, and when the user stopped receiving a program.

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.
摘要翻译： 使用不同级别的安全性的多个公钥/私钥对来提供高水平的安全性，同时仍然允许加密信息的快速处理。 较低安全级别包括长度较小的密钥，相对频繁地更改，并且需要较少或较少的资源来实现其功能。 当需要更改低安全性的密钥对时，使用比较低安全级别密钥更高的安全级别的密钥对（即较长的密钥）将新的较低安全性的公钥传输到使用这些密钥的设备 。 更高安全性的密钥又可以以低于较低安全密钥的频率进行更改。 较高安全性的密钥需要更高级别的资源来执行编码操作。 使用升级级别的安全性的密钥替代较低安全性密钥（其中较高安全性密钥需要更多资源）的方法更安全，并且被替换的次数低于较低安全密钥，可以跟随多次 需要创建公共密钥使用的层次结构，结果是可以在整个系统安全性较高的情况下快速执行较低安全性的操作。

摘要： A method of generating a Personal Identification Number (PIN) between a first device and a second device in a network is provided. The method includes securely receiving information of input choices of the second device and random numbers assigned to the input choices at the first device. At the first device, the PIN is generated from the random numbers, and instructions are provided directing an entry of the input choices on the second device. At the second device, the input choices are entered. The second device is operable to generate the PIN from the input choices and the random numbers if the input choices are entered as instructed.

摘要： A content moving device which enables providing content stored on a first user device, such as a DVR, in a first format and resolution to be provided to a second user device, such as a portable media player (PMP) in a second format and resolution. The content moving device identifies content on the first user device as candidate content which may be desired by the PMP and receives the candidate content from the DVR. The content moving device transcodes the candidate content at times independent of a request from the PMP for the content. The content moving device may provide a list of available transcoded content to the PMP for selection, and provide selected content to the PMP. The content moving device may also provide information relating to any protection schemes of the content provided to the PMP, such as DRM rights and decryption keys. The content moving device performs the often computationally intense and time consuming transcoding of user content to enable the user to move content between different user devices in a convenient manner.
