      We present a fast, synchronous, cryptographic protocol by means
      of which Alice can send Bob a stream B, with assurance of
      non-repudiation of reception of B or any prefix of it by Bob.
      Bob, on the other hand, can prove to any third party the origin
      of B or any prefix of it. While the protocol's synchronous
      nature may prevent its use in some broadcast-type applications,
      its speed and mutual non-repudiation capabilities make it well
      suited for several e-commerce applications.
