摘要： A computer system and method are disclosed for generating a certificate that can be validated against a trusted hardware subsystem within a computer system. A security subsystem is established within the computer system. A master key pair including a master public key and master private key are established. The master private key is stored in protected storage within the security subsystem such that the master private key is inaccessible outside of the security subsystem. Generation of a self-verifying certificate is requested. A user of the computer system is then prompted to enter an authentication code in response to the request for generation of the certificate. A certificate is generated utilizing the master key pair only in response to a correct entry of the authentication code. The certificate is used only internally within the computer system.

摘要： A computing system includes a motherboard including one or more connection subsystems, each of which includes a port connector and a device interface circuit conditioning signals transmitted or received through the port connector. The port connector includes a connection-sensing terminal, which is connected to ground through a cable, and which is allowed to float to a voltage supplied through a pull-up resistor when the cable is disconnected. The motherboard also includes a main voltage plane supplying electrical power to a separate voltage plane for each device interface circuit only when a cable is connected to the port connector which is also connected to the device interface circuit.

摘要： A data processing system and method are disclosed for permitting only preregistered client computer hardware to access a service executing on a remote server computer system. A log-in token is established including a unique identifier which identifies a particular client computer hardware. The client computer hardware logs-on to the server computer system. Subsequent to the client computer hardware logging-on to the server computer system, the client computer hardware attempts to access the service. During the attempt, the client computer hardware transmits the log-in token to the server computer system. The server computer system utilizes the unique identifier included within the log-in token to determine if the client computer hardware is registered to access the service. In response to a determination that the client computer hardware is registered to access the service, the server computer system permits the client computer hardware to access the service. In response to a determination that the client computer hardware is not registered to access the service, the server computer system prohibits the client computer hardware from accessing the service.

摘要： A remote mobile unit (MU) including a radio device is provided with an ability to communicate through a LAN by remote association with an access point (AP) that is out of range for communication with the radio device of the remote MU. The remote MU transmits a quest frames that is received and retransmitted by one or more intermediate MUs until a connection is made with the AP. Each of the intermediate MUs adds an identifying address to the request, forming a path that is used in both directions to transmit a response from the AP to the remote MU and to transmit data between the AP and the MU.

摘要： A method and system for enabling security attestation for a computing device during a return from an S4 sleep state. When the computing device enters into the S4 state following a successful boot up, the attestation log is appended to the TPM tick count and the log is signed (with a security signature). When the device is awaken from S4 state, the BIOS obtains and verifies the log created during the previous boot. The CRTM maintains a set of virtual PCRs and references these virtual PCRs against the log. If the values do not match, the return from S4 state fails and the device is rebooted.

摘要： A method for authentication in a computer system includes registering a biometric template in the computer system, thereafter, verifying the authenticity of the registered biometric template and then comparing the biometric template with a biometric image of a user if the biometric template is authentic. If the user's biometric image matches the biometric template, the computer system will continue to boot.

摘要： A method and system for conserving battery strength of a mobile node, such as a laptop computer, on a wireless local area network (WLAN). The mobile node transmit symbols, which are units of data, during transmission cycles to maintain a connection with the WLAN. A battery charge level of the mobile node is measured. As the battery charge level drops below pre-defined levels, a frequency of symbol transmission for the mobile node is reduced. The reduction of the frequency of the symbol transmission results in lower power demands by a transmitter chipset of the mobile node. Thus, the mobile node is able to prolong the life of the battery of the mobile node.
