Signature Creation and Validation Service. "eGov-Bus is funded by the European Community under the Information Society Technologies priority of the Sixth Framework Programme" Motivation Within eGovernment processes creating and validating digital signatures play an important role.

Signature Creation and Validation Service

Therefore eGov-Bus is providing adequate support for the creation and validation of signatures via a signature creation and validation web service. This service addresses following security requirement: Users, APG (advanced process generator), and Government applications want data to be signed, and may want data to be signed in a legally relevant way. Description The signature creation and validation service (SCVS) is based on modules of an Austrian eGovernment open source program and extends these basic modules by XAdES capabilities and CMS signature creation. In the following table features of the signature validation service are listed.

XML Signature Best Practices

In this situation incoming messages should be assumed to be possibly hostile with the concern that a single poison message could bring down an entire set of web applications and services. Implementation of the XML Signature specification should not always be literal. For example, reference validation before signature validation is extremely susceptible to denial of service attacks in some scenarios. As will be seen below, certain kinds of transforms may require an enormous amount of processing time and certain external URI references can lead to possible security violations.

Best Practice 1: Implementers: Mitigate denial of service attacks by executing potentially dangerous operations only after successfully authenticating the signature. Bouncycastle.org.

XML Security Library: XML Digital Signature Online Verifier. Signing an XML document using XMLDSIG. This page demonstrates how to create a digital signature in XML.

Signing an XML document using XMLDSIG

This is a simple [sic] example of an enveloping signature where we sign a straightforward text string inside an XML document. 2012-05-09: For an example of a enveloped signature, see Part 2. To make a digital signature, you need a private key. Our example uses the 1024-bit RSA private key for Alice from RFC 4134 [SMIME-EX]. We use our CryptoSys PKI Toolkit to carry out the necessary computations. We give full details of the exact data to be processed at each stage in order to produce the final signed XML document.

For advanced users: If this is too simple for you, see our page on XML-Dsig and the Chile SII where we look in detail at creating digital signatures in XML documents using the standards for electronic invoices set by the Servicio de Impuestos Internos (SII) of Chile.
