摘要：
A system comprises a first operating environment and a second operating environment. The first and second operating environments exchange information in encrypted form using a shared encryption key (K3). The first and second operating environments cooperate to change the encryption key K3 using another shared encryption key (K4). The encryption key K4 is changed upon the encryption key K3 being changed.
