摘要:
A wireless network system and a communication method, where an external network device easily and temporarily logs in and out of the wireless network. A key management device of the wireless network system includes a limited communication unit that receives encryption information from a wireless network device, a storage unit that stores authentication information for authenticating the wireless network device, and a key creating unit that creates an encryption key using the received encryption information to allow the wireless network device to log onto the wireless network. The key creating unit also transmits the created encryption key to the wireless network device.

A network device for automating a TakeOwnership process includes a public key generation unit for generating a public key and a private key by employing public key cryptography, a storage medium write/read unit for writing the generated public and private keys on a storage medium and for reading the public and private keys written on the storage medium, and a control point/security console switching unit for selecting one of a security console function providing an access authority for a predetermined device and a control point function controlling operation of the predetermined device, after authentication of a user using the private key stored on the storage medium. Thus, by employing public key cryptography in which a digital signature is created using the private key stored on the storage medium, such as a smart card, and is verified by the public key, the user can securely operate home network equipment as well as enjoy a convenience in use.

A wireless universal serial bus (WUSB) security is provided. A method of providing a session key to be used during a session between a host and a device creates the session key based on a seed key stored in a region that is not allowed by the device; and provides the session key to the device. Therefore, a user does not need to distribute information necessary for creating the session key (i.e., a connection context) to a guest device.

An apparatus and method are provided for safely switching among security consoles and acquiring ownership with respect to a controlled device by executing an electronic signature using a smart card. An apparatus for executing a security function using a smart card includes: a smart card read unit which acquires a public key of a security console by reading the smart card; an authentication unit which verifies validity of an electronic signature transmitted from the smart card by using the public key of the security console; and a switching unit which switches the apparatus to a security console capable of acquiring ownership with respect to a controlled device if the electronic signature is determined to be valid.
摘要:
A virtualization apparatus and a method for controlling the same. In a method for controlling a virtualization apparatus including a plurality of domains, a sub domain transmits an input/output (IO) request for a hardware device to a main domain, and the main domain controls whether or not the IO request accesses the hardware device according to a resource needed to perform the IO request.
摘要:
An apparatus and method of providing security information in a virtual environment that supports a plurality of operating systems. The plurality of operating systems include at least one secure operating system in which applications whose safety has been verified are installed, and at least one normal operating system in which applications whose safety has been not verified are freely installed. The server operating system may provide security information corresponding to an operating system in which an application executed as foreground is installed, to provide information indicating whether an application is operated in a secure operating system, to a user.

A method of intrusion detection in a terminal device that supports driving of a plurality of operating systems, is provided. The method includes collecting at a first operating system of the plurality of operating systems intrusion detection data for analyzing whether there is an intrusion in at least a second operating system of the plurality of operating systems; and performing at the first operating system an intrusion detection with respect to the at least a second operating system using the collected intrusion detection data.
