The ADSS Server Signing Service can create PDF digital signatures or all common ETSI PAdES formats (PAdES Part 2,3,4) and it can also create and apply visible signature appearances where requested. While other digital signature approaches have quite limited signature appearance functionality, the ADSS Server Signing Service includes a sophisticated and yet easy to use signature appearance designer. This enables administrators to create visible signatures that are optimised for their business purpose.
Hardware Security Modules (HSMs) are a fundamental part of a high trust solution. They offer fast, secure processing of private keys, which ensures that keys cannot be created, copied, changed or deleted without appropriate permission or stolen without being noticed. They also off-load the processing cost of digital signatures for high performance systems such as time stamping servers or certificate validation servers.
This article describes why RFC3161 compliant Time Stamp Authority (TSA) servers are needed and what to look for when choosing a Timestamp Authority (TSA) server. ETSI TS 101 861 and TS 102 023 also places important requirements for TSA services providers and these are also considered in this hot topic.
ADSS Server v4.8+ supports clever integration with Active Directory and other LDAP compliant directories to enable seamless and automatic management of each user’s digital certificate, including generation, revocation and re-issuance.
SSL Trust Issues
India's National Informatics Centre (NIC) has now joined the infamous Dutch CA DigiNotar in issuing fake and unauthorized digital certificates, yet again damaging the faith we place in Certification Authorities to provide high trust identity assurance.
Using PKI-based digital certificates has become a widely accepted means of electronic identity authentication for all kinds of purposes, from logical/physical access control to document signing, server authentication for e-commerce sites and software code authentication.
PDF documents have been common use within business for many years. Protecting PDFs against change is fast becoming a hot topic. Digitally signing PDFs with a certifying signature protects the content and also shows who signed or approved the document. This article explains how you can easily digitally sign PDFs, it covers what is needed to electronically sign PDF documents and the different types of PDF signatures.
Getting a document approved and signed-off is a crucial part of any business, be it an order, sales contract, claim forms, internal HR documents or any other type of document that needs to be clearly agreed and approved preferably with a clear audit trail.
PEPPOL is a large-scale European Commission project, working on allowing any company in the EU to be able to communicate electronically with any EU governmental institution for all procurement processes.
Within Europe a new digital signature format “PAdES” is gaining traction. PAdES stands for “PDF Advanced Electronic Signatures” and is a set of standards published by ETSI (TS 102 778 parts 1 to 5) to support European requirements for electronic signatures. The purpose is specifically for creation of long-term signatures that are verifiable for years or even decades.
