Abstract
An on-line value bearing item (VBI) printing system that includes one or more cryptographic modules and a central database is disclosed. The cryptographic modules are capable of implementing the USPS Information Based Indicia Program Postal Security Device Performance Criteria and other required VBI standards. The modules encipher the information stored in the central database for all of the on-line VBI system customers and are capable of preventing access to the database by unauthorized users. Additionally, the cryptographic module is capable of preventing unauthorized and undetected modification, including the unauthorized modification, substitution, insertion, and deletion of VBI related data and cryptographically critical security parameters.
