The Link-BR2 Project, Developed by FAB and AEL with Support from Kryptus, Advances in the Brazilian Military Sector, Ensuring Encrypted Communication Between Aircraft and Bases with Cutting-Edge Cybersecurity. Expansion to Army and Navy Is Underway.
As cybersecurity technology grows worldwide, Brazil has intensified its efforts in the defense sector, particularly with the development of Link-BR2.
This ambitious project from the Brazilian Air Force (FAB) is coordinated by AEL Sistemas in collaboration with Kryptus and promises to transform the security of communications between aircraft and military ground bases in the country.
In addition to reinforcing national defense, the system uses cutting-edge encryption and cybersecurity, a step that places Brazil on the path to excellence in military technology.

With tests completed and integration in its final phase, Link-BR2 is already in operation with the F-5M aircraft but will soon be expanded to new military platforms, elevating the security level of Brazilian tactical operations. See how Brazil is investing in its technological sovereignty and ensuring information protection.
How Link-BR2 Works
Developed by AEL Sistemas and in operation since 2020, Link-BR2 is a tactical data link system designed to perform encrypted real-time communication between aircraft and FAB ground stations.
In 2024, the system moved to a new testing phase, which included the integration of airborne cybersecurity and encryption solutions developed by Kryptus, a specialist in digital security.
According to FAB, the Link-BR2 enables classified tactical information to be exchanged in real-time, with security and authenticity guaranteed, being essential for coordination in military operations.
Fernando Farias, project manager at Kryptus, states that active encryption in the aircraft radios is one of the most important milestones for ensuring the system’s final certification.
“Kryptus developed communication and security protocols that range from protecting ground terminals to embedded encryption in radios, ensuring secure information transmission,” Farias explains.
Kryptus and AEL Sistemas: Strategic Partnership for Cyber Defense
With over 40 years of experience, AEL Sistemas is a Brazilian company engaged in the development and manufacturing of electronic systems for military use, including Link-BR2.
Kryptus is recognized for its role in protecting classified data and for its innovative technologies, having developed Typhon, the country’s first autonomous cyber defense system.
According to Ismail Rodrigo Müller, program manager at AEL Sistemas, the partnership between AEL and Kryptus is a pillar of support for Brazil’s technological development: “Kryptus provides us with cutting-edge cybersecurity technology, from design to validation of cryptographic boards and implementation in radios and ground systems,” he emphasizes.
Main Features of the Security System
The cybersecurity system of Link-BR2 consists of various elements that ensure the confidentiality, integrity, and authenticity of information. Some of the technologies implemented by Kryptus include:
1. Crypto Computer: an essential component of the National IFF Mode 4 Project (IFFM4BR), ensures interoperability among different combat platforms (airborne, ground, and maritime), securely.
2. Credentialing, Authentication, and Authorization System: only authorized users and terminals can access the Link-BR2 network, a security layer that protects tactical communications.
3. Operating System and Network Security: robust protection barriers against cyberattacks ensure the security of military operations.
4. Secure Distribution of Keys and Files: cryptographic keys and files are distributed with high security to maintain data integrity and confidentiality.
5. kNET HSM and KeyGuardian: these tools protect the certifying authorities and create cryptographic keys that are impossible to decipher, enhancing the protection of communications.
As Farias explains, these elements provide an extra layer of protection for the system and ensure the effective execution of FAB’s military operations.
Final Testing Phase and New Developments
With final integration nearing completion, the Link-BR2 project will start to encompass new combat and defense platforms.
According to the portal Poder Aéreo, one of the goals is to expand the use of Link-BR2 to the new F-39 Gripen fighters and to other defense forces in Brazil, such as the Army and the Navy.
Discussions with the Navy are already advanced, while the Army is also interested in adopting the system as Brazil’s standard tactical datalink.
For Fernando Farias, Link-BR2 represents a milestone for Brazil: “When it reaches maturity, it will be one of the most secure and advanced data link systems in the world, placing Brazil at the forefront of defense technology.”
According to him, the fully national technology demonstrates a commitment to the country’s sovereignty.
Kryptus and Its Innovation Journey
Founded in Campinas (SP) in 2003, Kryptus is recognized as a Strategic Defense Company (EED) by the Ministry of Defense and provides cybersecurity solutions for the public and private sectors.
The company is known for its global operations and for cybersecurity defense projects like Typhon, aimed at protecting military networks and critical infrastructure. In 2024, Kryptus was once again recommended as a strategic provider of digital security and encryption.
The Role of AEL Sistemas in the Brazilian Defense Sector
Also recognized for its work in defense and space, AEL Sistemas develops command and control systems for the Armed Forces of Brazil, such as Link-BR2, STERNA, and SIC2MB.
With its headquarters in Rio Grande do Sul, AEL is now seen as a reference in defense technology in Brazil and continues to partner with FAB on high-complexity projects of strategic relevance.
The company contributes to the development of essential technologies for the national security system and supports FAB in implementing robust solutions for military communications.
The Link-BR2 project brings benefits that go beyond digital security, as it signifies the advancement of technological sovereignty and strengthens Brazil’s military capability.
