The threat of 'Store Now, Decrypt Later' (SNDL) has accelerated the adoption of PQC. Adversaries are currently capturing encrypted traffic with the intention of decrypting it once a cryptographically relevant quantum computer (CRQC) becomes available.
Lattice-Based Encryption | The New Standard
Unlike RSA, which relies on the difficulty of integer factorization, lattice-based cryptography relies on the 'Learning With Errors' (LWE) problem. This problem is believed to be hard for both classical and quantum computers.
The Migration Challenge | Updating the Global Stack
The transition to PQC is not a simple software update. It involves larger key sizes and different computational overheads, which can break legacy protocols and increase latency in handshake processes.
