KEM combines X25519 and Kyber-768 algorithms in a single process to ensure a secure connection. Experts believe that in the near future quantum computers will be able to crack existing encryption schemes, and this technology is Google’s preemptive response to the threat.

what is known

The new encryption is designed to share confidential data with symmetric encryption while establishing secure network connections.

• X25519 is an elliptic curve algorithm already used to establish a secure connection.
• Kyber-768 is a quantum resistant algorithm approved by NIST (US National Institute of Standards and Technology) for post-quantum cryptography.

These algorithms work together to allow two people to generate a shared secret key so they can communicate privately.

Do it now so you don’t regret it later.

Rebecca Krauthamer, QuSecure co-founder and chief product officer, believes this technology is useful and necessary today for two reasons, although it may sound futuristic. First, data is captured today for further decryption in the future. Second, the advent of powerful quantum computers should be viewed as something that will come without warning, not as a specific threat that will arrive at a specific date. They can appear after 50, 10 or 5 years. In any case, it will come as a surprise to most people, because scientific progress is characterized by sudden leaps.

Krauthamer believes that data that will be important in the future should be protected today with quantum resistant cryptography. He also reminds us that last year, Joe Biden signed the law HR7535 on preparation for the cyber security of quantum computing in the USA. He’s demanding that US government agencies start moving to quantum resistant cryptography now.
