Distributed Systems Security

Specification and development of Electronic Commerce Applications based on EDIFACT. Development of EDIFACT security messages and others.

Study of the security control mechanisms in Internet, computer networks and distributed systems in general.

The group holds the Spanish CERT (Computer Emergency Response Team) to coordinate the Internet security incidents.

Security policies choices have been analyzed, and specific security policies for security targets have been defined. Security products are tested and evaluated.

Tools for secure authentication and certification have been developed and an infrastructure for public key certification (Certification Authority, CA) has been set up in coordination with other CA in Europe.

A version of the secure transport layer has also been implemented, according to the ISO 10736 specification: Transport Layer Security Protocol.

Now, we are working to introduce security in WWW, Electronic Commerce and EDI applications (Electronic Data Interchange), using electronic signatures and certification authorities (CA).
