Jaume I University

Projects at UJI is intended to agregate all the projects implemented or with the Universitat Jaume I's collaboration regarding open source.







eSurvey

The main objective for this project is to have a software that allows the user to do telematic surveys and voting with the maximum anonymity guarantees. This is a fault-tolerant system, completely anonymous (Is based on blind signature) and non traceable (It uses a Controlled Latency Network). The integration is really simple as far as the user only needs a browser with JS support thus, the cost is also really low.

CryptoApplet

CryptoApplet is a Java applet for advanced digital signature creation. The procedure is very simple: given a data input and a configuration determined by the server, the web client will create a digital signature of the data, and a representation of the signature is obtained in the format specified in the configuration.

The signature representation formats supported by CryptoApplet are the following:

  • Raw signature.
  • CMS/PKCS#7.
  • XAdES-X-L in Digidoc format.
  • PDF signature.

Clauer

The porpose of the Clauer project is to provide a way to use, store and transport X509 certificates with minimum cost.

One of the major drawbacks of digital signatures is that private keys and certificates cannot be easy carried. There are a lot of specific devices to transport cryptographic objects, but they arent cheap, and usually they serve only to this pourpose. The aim of this project is to solve this problem with practically null cost. In the link below, we present the project form a practical point of view, you can read some information, or you can test the software now.

This is a software that convert a simple CDROM or an USB flash disk in an authentication tool, capable of perform authentication with several levels of security, in particular with X509 certificates.
The result is that you carry, with a simple USB "pen drive", all your x509 certificates and use it in a transparent way.

Anybody can download the software and use it. Restrictions apply only to redistribution.
Software is avaiable for:

  • Windows:
    • CryptoAPI: IExplorer, Outlook, and any program that uses CryptoAPI,
    • PKCS11: Mozilla Firefox,
  • Linux: Mozilla Firefox

eAuthoring

eAuthoring is a Windows program capable of generating a PDF file electronically signed using any application that is capable of printing. In addition it maintains one or more classified backups of generated PDFs.

Its main features are:

  • The signature can be verified with Adobe Acrobat Reader, you do not need to install an additional program to verify the signature.
  • The use is extremely simple.
  • You can send the signed document to your contacts through an integrated contact list.
  • You can store documents in local or external repositories for maximum security in the signed document storage.
  • It is integrated with the Windows CryptoApi architecture so it works with certificates installed in the Windows Store as well as with certificates stored into cryptographic devices.

Its use is extremely simple:

  • You generates a document with any "printing capable" application. It could be a plane, a text, an invoice, etc.
  • Print the document with the used program and select the eauthoring named printer.
  • Stablish the storage options through the menu: recipient and date.
  • Click "Save" button
