Abstract: A method for authenticating a message in a network is provided. The method includes a step of generating, in a sink device, a private key and a public key. The private key includes a plurality of sub-private keys. The method further includes a step of generating, in the sink device, a signature for the message. The signature includes a sub-private key and an authentication path associated with the sub-private key in a hash tree. The hash tree is constructed during the generation of the sub-public keys.

Abstract: In one embodiment of the present invention, a system for dynamic content distribution and grouping includes a server for providing a plurality of content channels, at least one tuning/decoding means for receiving/decoding at least one of the plurality of content channels, and at least one respective display means for displaying the at least one received/decoded content channel. In such embodiments of the present invention, the server is configured to dynamically configure the at least one tuning/decoding means to receive/decode at least one of the plurality of content channels. More specifically, in embodiments of the present invention, the server dynamically configures the at least one tuning/decoding means by communicating a channel change command to the at least one tuning/decoding means over a dedicated radio-frequency channel or, in an alternate embodiment, using an internet protocol.

Abstract: A computer system and a method for tracking information flow are provided. The computer system divides an information flow tracking task into two decoupled tasks executed by two procedures. The first procedure emulates execution of instructions and divides the instructions into code blocks according to an instruction executing sequence. The first procedure translates the instructions of the code blocks into information flow codes and transmits them to the second procedure. The first procedure further translates the instructions into dynamic emulation instructions and executes the dynamic emulation instructions to generate addressing results of the dynamic addressing instructions. The second procedure executes the information flow codes according to the addressing results to emulate the instructions of the code blocks. Moreover, the method also tries to reduce the amount of data transmission between the two procedures when the first procedure executes the emulation task.

Abstract: A fan apparatus has a frame, a motor and at least one fan blade part. The frame has a through chamber where the motor and the fan blade assembly are configured. The fan blade assembly has a stationary blade and a moving blade. The stationary blade is fixed inside the chamber to go around the motor and has multiple first radial blade parts. The moving blade is coupled to a shaft of the motor and has multiple second radial blade parts. When each first blade part is corresponding to the corresponding second blade part, a first included angle is formed between each first blade part and the corresponding second blade part. Therefore, a pair of the stationary blade and the moving blade enhances the wind pressure of the fan apparatus.

Abstract: A method of accelerating heat dissipation for a compact electronic device has steps of defining a heat dissipation opening as an airflow emission opening on a compact electronic device; defining connection port and slot as intake openings on the compact electronic; and extracting air from the airflow emission opening to make cold air effectively enter the intake openings. Therefore, the cold air thoroughly passes multiple heating elements and then to go out via the airflow emission opening. In this way, to force convection is achieved, so as to enhance cooling efficiency.
