JEP 497: Quantum-Resistant Module-Lattice-Based Digital Signature Algorithm

Enhance the security of Java applications by providing an implementation of the quantum-resistant Module-Lattice-Based Digital Signature Algorithm (ML-DSA).

(So its the same anti-quantum shit like 496 but for signatures.)

🔐 Why Is This Important?

• Traditional algorithms like RSA or ECDH will be broken by quantum computers (via Shor’s algorithm).

• ML-KEM is a quantum-safe alternative for key exchange, approved by NIST.

• This ensures secure communication between two parties — even in the post-quantum world.

🔧 What Is ML-KEM?

• ML-KEM = Module-Lattice Key Encapsulation Mechanism

• Based on the Kyber algorithm (winner of NIST’s Post-Quantum Cryptography standardization)

• Allows secure key agreement over an insecure channel.

📦 What Java 24 Adds

• New interface: javax.crypto.KEM

• New key agreement algorithms:

  • "ML-KEM-512"

  • "ML-KEM-768"

  • "ML-KEM-1024"

These can be used for establishing shared secrets — safely and quantum-resiliently.
