Method and apparatus for providing session key for WUSB security and method and apparatus for obtaining the session key

摘要

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.
