   *Notational Conventions*

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   specification are to be interpreted as described in [RFC2119].

   Certain security-related terms are to be understood in the sense
   defined in [RFC4949].  These terms include, but are not limited to,
   "attack", "authentication", "authorization", "certificate",
   "confidentiality", "credential", "encryption", "identity", "sign",
   "signature", "trust", "validate", and "verify".

   Unless otherwise noted, all the protocol parameter names and values
   are case sensitive.

2.  JOSE Authentication
