Efficient and Quantum-Safe Internet Key Exchange Protocols for Satellite Communications

This paper studies cryptographic key exchange in satellite communications, which requires specific solutions because the satellite context presents unique challenges, particularly concerning onboard resource constraints and long transmission latency. We address these challenges by considering the...

Preparing for the Quantum Era: Post-Quantum Cryptography Webinar for Security Leaders

Most organizations assume encrypted data is safe. But many attackers are already preparing for a future where today’s encryption can be broken. Instead of trying to decrypt information now, they are collecting encrypted data and storing it so it can be decrypted later using quantum computers. Thi...
