+RSE based DICE Protection Environment
+-------------------------------------
+
+The ``DICE Protection Environment (DPE)`` [8]_ service makes it possible to
+execute |DICE| commands within an isolated execution environment. It provides
+clients with an interface to send DICE commands, encoded as CBOR objects,
+that act on opaque context handles. The |DPE| service performs |DICE|
+derivations and certification on its internal contexts, without exposing the
+|DICE| secrets (private keys and CDIs) outside of the isolated execution
+environment.
