Mobile signatures are electronic signatures which are created using a mobile device and rely on signature or certification services in a location independent telecommunication environment. They allow signatory mobility beyond fixed, secure desktop workstation with trusted, personal signing equipment.
How Mobile Signature works – SDX Composer
Wireless PKI (WPKI) - mobile user authentication and electronic signatures
The European Union Electronic Signature Directive (1993/93/EC) provides a framework for the harmonization of legal, trust and technical aspects of electronic signatures. EESSI (European Electronic Signature Standardization Initiative) co-ordinates Industry and European Standards Bodies to provide an agreed framework and specifications for an open, market-oriented implementation of the Directive. Since then, several national eID projects started in Europe to provide e-Government services to citizens based on strong authentication and digitally signed transactions and documents.
The SDX (Signed Document eXpert) electronic signature integration and management product suite developed by E-Group. It fully conforms to the EU Directive and general PKI standards. The SDX product suite components support application integration in a very flexible way on both client and server sides.
The mobile phone is a Personal Trusted Device for electronic security in all situations where strong authentication and nonrepudiation of electronic signatures are needed.
E-Group offers mobile digital signatures in a centralized authentication framework, based on a Mobile Signature Service Provider (MSSP). The MSSP provides its services in an easy-to-use standards based service interface, ideal for e-Government and other e-Services.
Centralized authentication using mobile digital signatures
Typically, e-services (e-Business, e-Banking, e-Government etc.) have their own user authentication methods. In this case users have different type of authentication methods for different services. This is, however:
The Mobile Signature Service Provider (MSSP) is a standards (ETSI MCOMM) based server software for centralized user authentication and transaction validation, which manages the whole transaction life-cycle of mobile digital signatures. The MSSP supports:
The mobile phone as a Personal Trusted Device
Mobile authentication and electronic signatures allow the user to access the services using the best possible user interface:
The mobile phone is used for digitally signing authentication and non-repudiation Mobile Signature Service Provider requests. The mobile phone is ideal for generating digital signatures, because:
