摘要： A system that provides secure transmission of data between a subscriber's PC and an online service provider (OLS) over an Ethernet WAN. The system includes a remote transceiver unit located at a subscriber site and connected to the subscriber's PC; a central transceiver unit located at a telephone central office and connected to the remote transceiver unit over a twisted pair network and also connected to a WAN; an authorization server that is connected to the WAN; and one or more OLSs, which may include Internet service providers, connected to the WAN. Security of transmission is provided through a method in which only subscriber transmissions directed to a session-specific OLS are allowed to pass through the central transceiver unit onto the WAN, and only unicast transmissions from authorized OLSs are allowed to pass through the central transceiver unit to the subscriber port of the remote transceiver unit. Broadcast transmissions are minimized in favor of unicast messages. The authorization server delivers the IP and MAC addresses of the session-specific OLSs and the subscriber's PC to the remote transceiver units.
摘要翻译：通过以太网WAN在用户的PC和在线服务提供商（OLS）之间提供数据安全传输的系统。该系统包括位于用户站点并连接到订户的PC的远程收发器单元; 位于电话中心局的中央收发器单元，并通过双绞线网络连接到远程收发器单元，并且还连接到WAN; 连接到WAN的授权服务器; 以及一个或多个OLS，其可以包括连接到WAN的因特网服务提供商。通过一种方法提供传输的安全性，其中仅允许指向特定于会话的OLS的用户传输通过中央收发器单元到达WAN，并且仅允许来自授权OLS的单播传输通过中央收发器单元远程收发器单元的用户端口。广播传输最小化，有利于单播消息。授权服务器将会话特定OLS和用户PC的IP和MAC地址传送到远程收发器单元。

摘要： A system that provides additional voice lines with data over a single two-wire subscriber loop. At the subscriber premise, one or more telephone instruments and data devices are connected to a digital modem into either a voice or a data interface. Analog voice signals are PCM sampled then packetized, and voice and data packets are transmitted to a CO modem over the subscriber loop. The CO modem depacketizes the voice packets into PCM format and transmits PCM voice information to a CO switch over a standard digital trunk interface. Data packets are routed to a data network. Voice packets are given transmission priority over data packets to ensures that voice is transported in the presence of data with low latency.
摘要翻译：通过单个双线用户回路为数据提供额外的语音线路的系统。在订户的前提下，一个或多个电话设备和数据设备被连接到数字调制解调器进入语音或数据接口。模拟语音信号被PCM采样，然后进行分组，并且语音和数据分组通过用户环路发送到CO调制解调器。 CO调制解调器将语音分组拆分为PCM格式，并通过标准数字中继接口将PCM语音信息传输到CO交换机。数据包被路由到数据网络。语音数据包被赋予数据包的传输优先级，以确保语音在存在低延迟的数据的情况下传输。

摘要： A system and method for securing data on a wireless device. A secured zone is defined by a boundary sensor. A data processing system is coupled to the boundary sensor and a wireless device. The data processing system includes a boundary controller for determining whether the wireless device has entered the secured zone. If the wireless device has entered the secured zone, a security controller queries the wireless device to determine whether the software stored on the wireless device has been subjected to unauthorized alteration. If the software has not been subjected to unauthorized alteration, the security controller enables the wireless device for operation within the secured zone.

摘要： A method for theft deterrence of a computer system is disclosed. The computer system includes a trusted platform module (TPM) and storage medium. The method comprises providing a binding key in the TPM; and providing an encrypted symmetric key in the storage medium. The method further includes providing an unbind command to the TPM based upon an authorization to provide a decrypted symmetric key; and providing the decrypted symmetric key to the secure storage device to allow for use of the computer system. Accordingly, by utilizing a secure hard disk drive (HDD) that requires a decrypted key to function in conjunction with a TPM, a computer if stolen is virtually unusable by the thief. In so doing, the risk of theft of the computer is significantly reduced.

摘要： A method for a plurality of key cache managers for a plurality of localities to share cryptographic key storage resources of a security chip, includes: loading an application key into the key storage; and saving a restoration data for the application key by a key cache manager, where the restoration data can be used by the key cache manager to reload the application key into the key storage if the application key is evicted from the key storage by another key cache manager. The method allows each of a plurality of key cache managers to recognize that is key had been removed from the security chip and to restore its key. The method also allows each key cache manager to evict or destroy any key currently loaded on the security chip without affecting the functionality of other localities.

摘要： A Trusted Computing Platform Alliance (TCPA) endorsement certificate is provided by comparing a trusted platform module (TPM) public key transmitted by an owner of the computing device to which the TPM belongs to a copy of the key as originally stored in a remote database prior to vending the device. If a match is found the certificate is created using the public key, and then sent to the owner of the computing device.

摘要： An echo cancellation arrangement is provided for decreasing the "singing" of a connection of a large number of telephone subscribers in a conference calling arrangement. This arrangement includes a means for inserting quiet code during time when the voice samples of incoming PCM data are zero or below a predetermined minimum threshold level. This helps decrease the amount of feedback which is amplified and output through the codec/filter to the listeners through the PCM network. An attenuation arrangement is also included which decreases the level of a summed signal of a summing node of the conference circuit. This sum signal is the combination of each of the conferees' speech. Attenuation of this signal prohibits excessive coupling of amplified feedback to each of the listening conferees.
摘要翻译：提供一种回音抵消装置，用于减少会议呼叫装置中大量电话用户的连接的“歌唱”。这种布置包括用于在输入的PCM数据的语音样本为零或低于预定的最小阈值水平的时间期间插入静音码的装置。这有助于通过PCM网络将通过编解码器/滤波器放大和输出的反馈量减少到听众。还包括减少会议电路的求和节点的求和信号的电平的衰减装置。这个和信号是每位与会者演讲的组合。该信号的衰减禁止放大的反馈过度耦合到每个聆听者。

摘要： A method and system for ensuring security-compliant creation and signing of endorsement keys of manufactured TPMs. The endorsement keys are generated for the TPM. The TPM vendor selects an N-byte secret and stores the N-byte secret in the TPM along with the endorsement keys. The secret number cannot be read outside of the TPM. The secret number is also provided to the OEM's credential server. During the endorsement key (EK) credential process, the TPM generates an endorsement key, which comprises both the public key and a hash of the secret and the public key. The credential server matches the hash within the endorsement key with a second hash of the received public key (from the endorsement key) and the vendor provided secret. The EK certificate is generated and inserted into the TPM only when a match is confirmed.
摘要翻译：一种用于确保制造TPM的签注密钥的安全兼容创建和签名的方法和系统。为TPM生成认可密钥。 TPM供应商选择一个N字节的秘密，并将N字节的秘密与支持密钥一起存储在TPM中。无法在TPM之外读取密码。秘密编号也提供给OEM的凭据服务器。在认可密钥（EK）凭证处理过程中，TPM产生一个签名密钥，其包括公开密钥和密钥的散列以及公开密钥。凭证服务器将签名密钥内的散列与接收到的公钥（来自认可密钥）和供应商提供的秘密的第二散列进行匹配。仅当匹配确认时，EK证书才会生成并插入到TPM中。
