If the link stability of neighboring node is over standard value, the routing controller transmits the packet to the neighboring node.

    Abstract: An apparatus and a method for generating a cryptographic key and an integrity key in a communication system are provided to implement a high speed key by generating an integrity key and a cryptographic key based on a twice kasumi calculation of a kasumi unit and parameters. An apparatus for generating a cryptographic key and an integrity key in a communication system includes a sub key separation unit(10), a selection unit(20), a kasumi unit(30), and a key data generation unit(40). The sub key separation unit performs a logical operation for subscriber key data and random input data of the same input bit and separates the calculated data into two sub keys. The selection unit selects one sub key according to a sort of key to be generated. The kasumi unit generates kasumi calculation data of a predetermined bit through the selected sub key and the subscriber key. The key data generation unit performs a logical operation for the subscriber key and the generated kasumi calculation data, and generates a cryptographic key and an integrity key of a predetermined bit through the calculated data by the logical operation.
