Abstract: The present invention relates to a Torus-Quorum based channel rendezvous method for directional antennas. A pair of directional antennas facing any side initially points to the other party mutually in one Torus-Quorum system cycle through a rotation closure attribute of a Torus-Quorum system; and a receiver and a sender switch to a same available channel according to frequency hopping sequences to realize channel rendezvous. In the Torus-Quorum based channel rendezvous method for directional antennas proposed in the present invention, the directional antennas are rotated based on the Torus-Quorum, and elements are ensured to coincide with each other within limited time through the rotation closure attribute of the Torus-Quorum system, i.e., directions are opposite, thereby effectively shortening channel rendezvous time of the directional antennas.

Abstract: A method and system for detecting brain activity may be disclosed, the method including performing multi-channel synchronous collections of brain electrical signals and cerebral cortex blood oxygen signals simultaneously and ensuring synchronicity of the collected signals among channels by collecting the signals at multiple locations simultaneously. A system may include a functional near-infrared light source emission module, which may employ the frequency division multiplexing technique. A multi-functional joint collection helmet may access the light source signal emitted from the emission module, then may be processed by a near-infrared detection module. Further, the near-infrared detection module may detect optical signals of the scalp, while a brain electricity detection module detects electrical signals of the scalp. Finally, a central control unit may synchronize data collected from the detected signals and may control a variety of functional modules and upload the data to a host computer.

Abstract: A method for starting a trusted embedded platform based on TPM industrial control includes taking a Core Root of Trust Measurement (CRTM) as a source of a trust chain and executing CRTM after electrifying an embedded platform; conducting trust measurement of BIOS and starting BIOS after passing measurement; BIOS measuring Bootloader and extending a measured value into PCR corresponding to TPM; after passing the measurement, transferring a control execution right to Bootloader; and Bootloader measuring OS kernel start process, recording a measured value into PCR of TPM, and executing a start flow of OS after passing the measurement. The method performs measurement before start of each part of a start process, and measured values are also stored in the PCR corresponding to TPM. When the start process is tampered by an attacker, an integrity measurement mechanism terminates the execution of a program, thereby ensuring the security of the embedded platform.
