Advanced Security Services and AAA over IP networks


Today there exist different solutions and services related with security, but they are highly heterogeneous and it is impossible to ensure a global and homogeneous system security solution. The definition of frameworks able to combine coherently some of the current security technologies, services and protocols seems to be a real need for current and next-generation information systems.


This research line is mainly intended to address security services as a whole, including technologies, protocols, architectures and definition of APIs, thus contributing to the deployment of complete and comprehensive system security solutions.

State of the art

Previous research in this line ended up among others with the design and deployment of PKI (Public Key Infrastructures) solutions in intra- and inter-domain scenarios (UMU-PKIv6, University of Murcia Public Key Infrastructure with IPv6 support) and the active collaboration in the OpenDiameter initiative.

Proposed research activities

Current research lines include, but are not limited to:

• Analysis of new security technologies, protocols and services, such as ECC (Elliptic Curve Cryptography), ANONsec (Anonymous IPsec), etc.

• New key management protocols: IKEv2 (Internet Key Exchange, version 2) and MOBIKE (IKEv2 Mobility and Multihoming).

• Design and deployment of advanced authentication and PKI services: cross certification, certificate path validation and building algorithms, provision of XML-based PKI front-end services, etc.

• Provision of XML- and Web-based advanced security services based on different standards, such as, XKMS (XML Key Management Specification), XACML (eXtensible Access Control Markup Language) or WS-Security (Web Services Security).

• AAA frameworks and related protocols (e.g., DIAMETER) and their integration with mobility scenarios (e.g., MIPv6 bootstrapping)

• Deployment of advanced security models in SIP (Session Initiation Protocol)
