Abstract
Various methods for device-to-device key management are provided. One example method includes receiving a communication mode change command requesting a mode change to device-to-device communications, and generating a local device security key based on a secret key and a base value. The local device security key may be configured for use in device-to-device communications. The example method may also include receiving a security key combination value, and deconstructing the security key combination value using the local device security key to determine a peer device security key. The peer device security key may be configured for use in device-to-device communications. Similar and related example methods and example apparatuses are also provided.
