+* Description:  Security interface for HTI framework will provide
+*        implementation of security functionality:
+*        - authenication (establishing security context),
+*        - integrity (generating Message Integrity Code),
+*        - confidentiality (message encryption/decryption).
+*        The interface and terms are based on the GSS API [RFC 2743].
