Interface SessionKeyStore

All Known Implementing Classes:
KeyStoreFS, SessionKeyStoreImpl
public interface SessionKeyStore
This interface declares methods to read and write a secret key used to conceal session data. This kind of key is used by team/group members but is never shared with the BAN. Implementations my use symmetric or one-way keys as session keys but symmetric is the simpler to implement.
