OpenTrust SPI: Signature & Proof Infrastructure

Integrated Management Interface for:

  • managing the Web service access accounts and service contracts
  • defining signature, timestamping and archiving profiles and policies
  • customizing server security and operating settings
  • piloting the different server instances (for redundancy and load balancing)

Signature and Proof management Web services used by the business applications are flexible to implement:


From a functional perspective:
  • simple APIs for signature and signature validation
  • advanced APIs for proof life cycle management (creation, addition, validation, consultation, extraction, sealing, archiving)
  • macro API for serial processing
From an operational perspective:
  • synchronous and asynchronous call modes
  • batch processing
  • interfaces for depositing/extracting large amounts of data

Technical Characteristics
