System and Method for Providing Security in a Wireless Communications System

A method for device operations, the method comprises:

• determining an initial key;
• generating a security key from the initial key;
• receiving secured information;
• producing radio resource allocation information from the secured information by applying the security key to the secured information, wherein the radio resource allocation information comprises a location of radio resource allocated to a communications device;
• and
• detecting for a transmission at network resources specified by the radio resource allocation information.

A communications controller comprising:

• a key generator configured to generate a security key from an initial key;
• a radio resource allocate unit configured to allocate a radio resource to a communications device, thereby producing radio resource allocation information;
• an encryption unit coupled to the key generator and to the radio resource allocate unit, the encryption unit configured to apply the security key to the radio resource allocation information to produce encrypted radio resource allocation information;
• and
• a transmitter coupled to the encryption unit, the transmitter configured to transmit the encrypted radio resource allocation information to the communications device.
