e-Notarisation & Secure Archiving

Why Ascertia?

There are very good reason0s for choosing Ascertia digital signature products for e-Notarisation and long-term archiving projects and these include:

  • Support for IETF LTANS Specifications:
    Ascertia is a leader in providing a secure archiving server which complies with the IETF Long-Term Archive and Notarisation Specifications (LTANS). Specifically Ascertia supports the XML Evidence Record Syntax (ERS) format as well as the XML/SOAP web services based Long-Term Archive Protocol (LTAP).
  • Apply electronic (digital) signatures to any type of document:
    Ascertia’s products offer the widest support for digital signature formats and standards and the greatest flexibility in how to implement these. The products support PDF, PDF/A, XML, PKCS#7, CMS, S/MIME and PKCS#1 signatures as required to sign business documents. German and other country qualified certificates can be used to provide advanced electronic signatures.
  • Verify existing electronic (digital) signatures to any type of document:
    Ascertia has the widest support for verification of digital signature formats as mentioned above. It also provides enhanced OASIS DSS-X Verification Reports and PEPPOL based quality ratings for signatures and associated certificates. All of this evidential information can be stored as meta data with the data objects being archived for later use.
  • Long-term signatures:
    Ascertia is a clear leader in creating long-term signatures - these can be verified many years in the future, an essential requirement for most government related data. ADSS Server supports all the ETSI XAdES and CAdES as well as latest PAdES (PDF format) profiles.
  • Multiple Signing Options
    Different applications have different needs for how signatures are created. Some require server-side batch-signing features, some require signatures to be created locally by users that have eID smartcards or secure USB tokens. Others even want key and certificate roaming solutions that offer virtual “smartcards”. Ascertia’s ADSS Server and Go>Sign Applet already provide all these options and more.
  • Multi-platform support
    Organisations cannot control which systems and browsers end-users will work with when submitting documents. It is essential the digital signature and encryption solutions work on any platform with any browser and support multi-lingual capability. Go>Sign Applet supports all Windows platforms as well as many Linux versions and has also been tested in various browsers.
  • Multiple Integration Options
    ADSS Server can be easily integrated with any business document production environment using our Watched Folder application called Auto File Processor, or our high-level Java and .NET ADSS Client SDKs or via direct XML/SOAP web service calls or even email integration using Secure Email Server.
  • High Performance, Scalability & Security
    ADSS Server can be run in load-balanced configuration to sign millions of documents in automated manner. All signature operations can be conducted in a secure Hardware Security Module (HSM) and multiple HSMs can be connected for performance and resilience purposes. All signing operations are securely logged in ADSS Server database.
  • More than just digital or electronic signatures
    Digital signature creation is only one part of the solution - there are also requirements for signature verification, trust anchor management, key management, certification, real-time certificate validation, time-stamping and secure long-term archiving. ADSS Server is unique in being able to address all these requirements in one multi-function server. All these services are based on leading industry standards including OASIS DSS & DSS/X (signing, verification and encryption), RFC3161 (timestamping), RFC2560 (OCSP validation), RFC5055 (SCVP validation), W3C XKMS (validation), etc.
