Abstract: A structure of light tube includes a main body, a power supply module, and at least one light emission element. The main body has first and second heat dissipation zones and an accommodation chamber. The main body has two ends respectively and electrically connected to two conductive terminals. The power supply module is received and retained in the accommodation chamber of the main body. The power supply module includes an enclosure forming a receiving space in which a power supply device is received and retained. The light emission element is coupled to the main body so that heat from the light emission element is directly drained through the main body, while the power supply dissipates heat through natural air flows without relying on the main body, so that there parts do not cause thermal interference with each other and the performance of heat dissipation is improved to thereby extend the lifespan of the light tube.

Abstract: An identity verification system applicable to a virtual private network architecture and method of the same are provided. The system is provided and connected to a virtual private network gateway. The virtual private network gateway is connected to a verification server via a network access server. The method comprises receiving an access request from a network via the virtual private network gateway, performing a process of identify verification and dynamic password verification on the access request by the verification server and via the network access server, rejecting the access request if the access request does not pass the identity verification, and authorizing the access request to access a corresponding virtual private network if the access request passes the identity verification, thereby enhancing security in accessing the virtual private network.
