The Link-BR2 project, developed by FAB and AEL with support from Kryptus, is advancing the Brazilian military sector, ensuring encrypted communication between aircraft and bases with cutting-edge cybersecurity. Expansion to the Army and Navy is underway.
As cybersecurity technology grows around the world, Brazil has stepped up its presence in the defense sector, especially with the development of Link-BR2.
This ambitious project of Air Force 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 strengthening national defense, the system uses cutting-edge encryption and cybersecurity, a step that puts Brazil on the path to excellence in military technology.

With tests completed and integration in the final phase, Link-BR2 is already in operation with F-5M aircraft, but will soon be expanded to new military platforms, raising the level of security 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 real-time encrypted communication between aircraft and FAB ground stations.
In 2024, the system moved into a new testing phase, which included the integration of onboard cybersecurity and encryption solutions developed by Kryptus, a digital security specialist.
According to the FAB, the Link-BR2 allows sensitive tactical information to be exchanged in real time, with guaranteed security and authenticity, being fundamental for coordination in military operations.
Fernando Farias, project manager at Kryptus, says that active encryption on aircraft radios is one of the most important milestones in ensuring final certification of the system.
“Kryptus has developed communication and security protocols that range from protecting terminals on the ground to encryption built into radios, ensuring the secure transmission of information,” explains Farias.
Kryptus and AEL Sistemas: strategic partnership for cyber defense
With over 40 years of experience, AEL Sistemas is a Brazilian company that works in the development and manufacture of electronic systems for military use, including the Link-BR2.
Kryptus is recognized for its role in the cyber protection of confidential data and for its innovative technologies, being the developer of 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 highlights.
Main features of the security system
The security system cybernetics Link-BR2 is composed of several elements that guarantee the confidentiality, integrity and authenticity of information. Some of the technologies implemented by Kryptus are:
1. Cryptocomputer: essential component of the National IFF Mode 4 Project (IFFM4BR), ensures interoperability between different combat platforms (air, land and sea), safely.
2. Accreditation, 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 cyber-attack protection barriers 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 certification authorities and create impossible-to-decipher cryptographic keys, increasing the protection of communications.
As Farias explains, these elements provide an extra layer of protection for the system and guarantee the effective execution of FAB military operations.
Final testing phase and new developments
With the final integration close to completion, the Link-BR2 project will now include new combat and defense platforms.
According to the portal Air Power, One of the goals is to expand the use of Link-BR2 to the new F-39 Gripen fighters and to other Brazilian defense forces, such as the Army and Navy.
Talks with the Navy are already advanced, while the Army is also interested in adopting the system as the Brazilian tactical datalink standard.
For Fernando Farias, Link-BR2 represents a milestone for Brazil: “When it reaches maturity, it will be one of the safest and most advanced data link systems in the world, placing Brazil at the forefront of defense technology.”
According to him, the entirely national technology is a demonstration of commitment to the country's sovereignty.
Kryptus and its trajectory of innovation
Founded in Campinas (SP) in 2003, Kryptus is recognized as 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 presence and cyber defense projects such as Typhon, aimed at protecting military networks and critical infrastructure. In 2024, Kryptus was once again recommended as a strategic supplier of digital security and encryption.
The role of AEL Sistemas in the Brazilian defense sector
Also known for its work in defense and space, AEL Sistemas develops command and control systems for Armed forces from Brazil, such as Link-BR2, STERNA and SIC2MB.
Headquartered in Rio Grande do Sul, AEL is now seen as a reference in defense technology in Brazil and continues to partner with the FAB on highly complex and strategically relevant projects.
The company contributes to the development of essential technologies for the national security system and supports the FAB in the implementation of robust solutions for military communications.
The Link-BR2 project brings benefits that go beyond digital security, as it marks the advancement of technological sovereignty and strengthens Brazilian military capacity.
