Abstract:
   An Oblivious Pseudorandom Function (OPRF) is a two-party protocol
   between client and server for computing the output of a Pseudorandom
   Function (PRF).  The server provides the PRF secret key, and the
   client provides the PRF input.  At the end of the protocol, the
   client learns the PRF output without learning anything about the PRF
   secret key, and the server learns neither the PRF input nor output.
   An OPRF can also satisfy a notion of 'verifiability', called a VOPRF.
   A VOPRF ensures clients can verify that the server used a specific
   private key during the execution of the protocol.  A VOPRF can also
   be partially-oblivious, called a POPRF.  A POPRF allows clients and
   servers to provide public input to the PRF computation.  This
   document specifies an OPRF, VOPRF, and POPRF instantiated within
   standard prime-order groups, including elliptic curves.
