Answer 1

There is another angle to this issue: Java delivered Permissions. In a context where the environment is controlled, one can assign a set of permissions to classes loaded with a secure class loader.

Java delivers 3 permissions objects related to the implementation of security:

PrivateCredentialPermission SecurityPermission AuthPermission

These can help improve and control access to functionalities when implementing a cryptography system. They are necessarily sufficient to make the system secure.
