  • Patent number: RE47364
    Abstract: In accordance with an embodiment of the present invention, a client device is protected against the execution of unauthorized software. The client includes a code authentication process that verifies the integrity of executable code, by generating and comparing a first hash value of the executable code with a known hash value of the original code. Furthermore, during boot-up, the client initializes a CPU exception vector table with one or more vector table entries. One or more, or all, of the vector table entries direct the CPU to execute the code authentication process prior to executing an event handler when an exception event occurs. Consequently, the code authentication process is virtually guaranteed to execute, thereby protecting against the execution of unauthorized code.

  • Patent number: RE47394
    Abstract: An electronic device has first and second circuitry. A wireless trigger signal at the first circuitry causes the second circuitry to power up to receive a second wireless signal. The second signal is according to a radio access technology for which the trigger signal is incompatible. In various embodiments the first circuitry (a low power receiver) may autonomously power up upon expiration of a timer. One or more security checks can be performed at various steps, each step conditional on passing the previous security check. The first circuitry operates at a lower power than the second circuitry which comprises a broadband radio. For example, the first circuitry might be a Bluetooth low energy receiver, and a trigger signal there causes a WLAN receiver to power up in order to download software/firmware updates or user content while the device is enroute between the manufacturer and end user.

  • Patent number: RE47621
    Abstract: A high security microcontroller (such as in a point of sale terminal) includes tamper control circuitry for detecting vulnerability conditions: a write to program memory before the sensitive financial information has been erased, a tamper detect condition, the enabling of a debugger, a power-up condition, an illegal temperature condition, an illegal supply voltage condition, an oscillator fail condition, and a battery removal condition. If the tamper control circuitry detects a vulnerability condition, then the memory where the sensitive financial information could be stored is erased before boot loader operation or debugger operation can be enabled. Upon power-up if a valid image is detected in program memory, then the boot loader is not executed and secure memory is not erased but rather the image is executed. The tamper control circuitry is a hardware state machine that is outside control of user-loaded software and is outside control of the debugger.

  • Patent number: RE47642
    Abstract: A unified system of programming communication. The system encompasses the prior art (television, radio, broadcast hardcopy, computer communications, etc.) and new user specific mass media. Within the unified system, parallel processing computer systems, each having an input (e.g., 77) controlling a plurality of computers (e.g., 205), generate and output user information at receiver stations. Under broadcast control, local computers (73, 205), combine user information selectively into prior art communications to exhibit personalized mass media programming at video monitors (202), speakers (263), printers (221), etc. At intermediate transmission stations (e.g., cable television stations), signals in network broadcasts and from local inputs (74, 77, 97, 98) cause control processors (71) and computers (73) to selectively automate connection and operation of receivers (53), recorder/players (76), computers (73), generators (82), strippers (81), etc.

  • Patent number: RE47717
    Abstract: A service controller on a computing device can be configured to redirect serial output over a network using HTTP. For example, the service controller can be configured with a web server that can receive the serial output and stream the serial output to a web browser over an HTTP connection. In some implementations, the HTTP connection can be a WebSocket connection, as defined by the HTML5 specification. In some implementations, a proxy server can be configured with a web server that can receive serial over LAN (SOL) output from multiple servers and stream the SOL to a web browser on a client device.

  • Patent number: RE47720
    Abstract: The present invention increases the available spectrum in a wireless network by sharing existing allocated (and in-use) portions of the RF spectrum in a manner that will minimize the probability of interfering with existing legacy users. The invention provides interference temperature-adaptive waveforms, and a variety of physical and media access control protocols for generating waveforms based on measurement and characterization of the local spectrum. The invention measures the local spectrum at a receiving node, generates an optimal waveform profile specifying transmission parameters that will water-fill unused spectrum up to an interference limit without causing harmful interference to primary and legacy transmitters using the same frequency bands, and enables simultaneous transmit and receive modes at a multiplicity of transceivers in a wireless network.

  • Patent number: RE47757
    Abstract: The invention is a system and method for identifying, assessing, and responding to vulnerabilities on a mobile communication device. Information about the mobile communication device, such as its operating system, firmware version, or software configuration, is transmitted to a server for assessment. The server accesses a data storage storing information about vulnerabilities. Based on the received information, the server may identify those vulnerabilities affecting the mobile communication device, and may transmit a notification to remediate those vulnerabilities. The server may also transmit result information about the vulnerabilities affecting the mobile communication device. The server may also store the received information about the device, so that in the event the server learns of new vulnerabilities, it may continue to assess whether the device is affected, and may accordingly notify or remediate the device.
