摘要：
A method, apparatus and computer program product are provided to provide cryptographical key separation for handovers. A method is provided which includes calculating a key based at least in part upon a previously stored first intermediary value. The method also includes calculating a second intermediary value based at least in part upon the calculated key. The method additionally includes sending a path switch acknowledgement including the second intermediary value to a target access point. The method may further include receiving a path switch message including an indication of a cell identification and calculating the encryption key based upon the indication of the cell identification. The method may further include storing the second intermediary value. The calculation of the key may further comprise calculating the key following a radio link handover. Corresponding apparatuses and computer program products are also provided.
