Aena as company

AENA (Aeropuertos Españoles y Navegación Aérea) is the leading airport operator in Spain. With an extensive network of airports and a strong international presence, AENA is recognised for its commitment to efficiency, safety and quality in the management of airport infrastructures that connect the world.

Need of project

Need to address security and authentication in freight credential management at cargo terminals The lack of an unforgeable system created security risks and operational delays. The implementation of Vottun Credentials on blockchain solved these problems by providing tamper-proof credentials and more efficient verification, guaranteeing the authenticity of carrier identities and improving security at airports managed by AENA.


Aena, the world’s leading airport operator by number of passengers, has launched a cargo management platform called VELLORE. This system manages the electronic exchange of information related to air transport operations between the members of the cargo community in the airports of the Aena Network.

AENA, one of the main airport managers in Spain, was looking to optimise and secure the freight transport processes at its cargo terminals throughout the country. To address this challenge, they partnered with Portel, a leading technology consultancy specialising in IT management systems for ports and airports.

The joint objective was to strengthen the security and robustness of access to cargo terminals by implementing blockchain technology. To achieve this, they chose to use Vottun Credenciales, a blockchain-based digital identity solution developed by the Vottun platform. This product enabled the creation of unforgeable credentials and immutable data records, providing an additional layer of trustworthiness.

The implementation of Vottun Credentials was carried out in a straightforward manner, without requiring in-depth knowledge of blockchain by Portel. A connection was established between the Vottun platform and the Vellore system, developed by Portel to securely manage and store the credentials of carriers accessing the loading docks of AENA airports.

This solution not only allowed for easy verification of identity at arrivals, departures and collections of goods, but also improved transparency in the airport freight transport processes. It also contributed to the strengthening of internal control and ensured a more secure environment at the airports managed by AENA.

Added Value

Unforgeable credentials: blockchain-based credentials are virtually unalterable, guaranteeing the authenticity of carriers' identities. This eliminates the possibility of forgery and fraud.

Immutable record: blockchain technology provides an immutable record of all transactions and activities related to credentials. This creates a reliable and transparent history that can be audited at any time.

Time savings: Identity verification is significantly streamlined, reducing waiting times and improving efficiency at airport check-in, check-out and pick-up.

Improved security: blockchain technology strengthens data security, protecting against cyber threats and ensuring the integrity of sensitive information.

Improved internal control: AENA can exercise greater internal control over credential management and access to cargo terminals, contributing to the overall security of airports.

Transparency: the solution brings greater transparency to credential management, which builds confidence both among carriers and in AENA's quality control.
