> Issue #8 http://trac.tools.ietf.org/wg/jose/trac/ticket/8 proposes adding an “spi” (security parameters index) header parameter to the JWS and JWE specifications.  This modification to the JOSE formats would allow for signaling that pre-negotiated cryptographic parameters are being used, rather than including those parameters in the JWS or JWE header.  This proposal has been written up as http://tools.ietf.org/html/draft-barnes-jose-spi-00.
