Abstract:
EZK is a tool for generating, handling, and securing electronic bills of lading. EZK implements the
cryptographic protocol suggested by Pagnoni and Visconti in (Pagnoni and Visconti, 2006), cryptographic
protocol that is based on a shipper-carrier-holder model. This protocol makes use of (a) blind merchandise
counts, or zero-knowledge counts, − that is, counts that do not reveal any information about the quantities
actually counted, − (b) secure timestamps, and (c) digital signatures. We show how EZK generates and
handles order e-BOLs and how the cryptographic techniques implemented in EZK make a number of
common fraud schemes impossible.
