Abstract
A module (2) for integrity protection of messages transmitted from a mobile software defined radio (SDR) terminal (1), the module provided with a confined cryptographic key K and arranged to receive loaded SDR-code. The module derives an integrity protecting key Rk from at least said cryptographic key K, and provides a periodic integrity protection on-line of generated messages using said key integrity protecting key Rk, and the integrity of said messages is verified by an integrity checking node (10) of the access network.
