Abstract: A communication method of virtual machines and a server-end system are provided. A virtual hardware address is assigned to a virtual machine when the virtual machine are established, wherein the virtual hardware address includes a tenant identity. A validation procedure for a packet is performed when the virtual machine desires to communicate with another virtual machine by transmitting the packet, so as to determine whether the virtual hardware addresses of the source-end and the destination-end in the packet have the same tenant identity. If the both virtual hardware addresses have the same tenant identity, the packet is transmitted to the another virtual machine.

Abstract: A wireless network client-authentication system and a wireless network connection method thereof are disclosed. The wireless network client-authentication system includes a network service system, a wireless router, and an electronic device. The network service system has an administrator interface module for managing a client list. The wireless router is used for uploading connection information to the network service system. The electronic device is capable of transmitting a signal via a first communication path and a second communication path. A connection module of the electronic device is used for logging in the network service system via the first communication path by a user account. The administrator interface module determines whether the user account is corresponding to the client list. If yes, the administrator interface allows the connection module to connect to the wireless router via the second communication path with the connection information.

Abstract: Display systems and methods with anti-eavesdropping function are provided. A glass and a display device are coupled. The glass has a right eye viewing component and a left eye viewing component. The display device alternately displays a real picture and a fake picture, and provides at least one control signal to the glass. The control signal triggers the right eye viewing component and the left eye viewing component of the glass to respectively switch between an open state and a closed state.

Abstract: A secure login method for a wireless local area network is implemented using a first wireless terminal that has already been logged in to the wireless local area network and that has obtained a settings value, and a second wireless terminal that has yet to be logged in to the wireless local area network and that has a public key and a secret key conforming to an asymmetric public key technique. The method includes: (A) enabling the second wireless terminal to send the public key to the first wireless terminal; (B) enabling the first wireless terminal to encrypt the settings value into an encrypted text using the public key and to send the encrypted text to the second wireless terminal; and (C) enabling the second wireless terminal to decrypt the encrypted text using the secret key so as to recover the original settings value that serves as a basis for logging in to the wireless local area network.

Abstract: In a login method for a wireless network with security settings, security settings data for a wireless local area network is provided in a portable wireless device (such as a remote controller) capable of two-way wireless transmission. When it is intended to log a new wireless network device in to the wireless local area network, the portable wireless device is operated to provide the security settings data to the new wireless network device. Therefore, the new wireless network device is able to log in to the wireless local area network upon completing security setup using the security settings data received from the portable wireless device. A wireless network system with security settings is also disclosed.
