METHOD AND SYSTEM FOR SECURED COMMUNICATION OF CONTROL INFORMATION IN A WIRELESS NETWORK ENVIRONMENT

摘要

The present invention provides a method and system for securely communicating control information in a wireless network environment. When a transmitting station has to transmit control information to a receiving station, the transmitting station determines whether the control information belongs to first type or second type. If the control information is the second type of control information, the transmitting station secures the second type of control information using a counter value, a CMAC value and security keys computed for protecting the second type of control information. Upon securing the control information, the transmitting station transmits the secured control information to a receiving station.
