Editing Simple public-key infrastructure (section)

'''Simple public key infrastructure''' ('''SPKI''', pronounced ''spoo-key'') was an attempt to overcome the complexity of traditional [[X.509]] [[public key infrastructure]].  It was specified in two [[Internet Engineering Task Force]] (IETF) [[Request for Comments]] (RFC) specifications – {{IETF RFC|2692}} and {{IETF RFC|2693}} – from the IETF [https://datatracker.ietf.org/wg/spki/about/ SPKI working group]. These two RFCs never passed the "experimental" maturity level of the IETF's [[Request for Comments#Status|RFC status]]. The SPKI specification defined an authorization certificate format, providing for the delineation of privileges, rights or other such attributes (called '''authorizations''') and binding them to a public key.  In 1996, SPKI was merged with '''Simple Distributed Security Infrastructure'''<ref>{{cite web|url=https://people.csail.mit.edu/rivest/sdsi10.html|title=SDSI – A Simple Distributed Security Infrastructure|website=people.csail.mit.edu|access-date=2017-03-15}}</ref> ('''SDSI''', pronounced ''sudsy'') by [[Ron Rivest]] and [[Butler Lampson]].
