Do We Need Quantum Leaps In Security? 〈UHD〉

: Moving away from "perimeter" security to a model where no user or device is trusted by default, regardless of their location.

: Uses error-correcting codes to create security. Do We Need Quantum Leaps in Security?

: Currently the frontrunner for NIST standards, relying on the complexity of finding shortest vectors in high-dimensional grids. : Moving away from "perimeter" security to a

The current security infrastructure relies on mathematical problems (like RSA and ECC) that are easy for classical computers to solve but would be trivial for a sufficiently powerful quantum computer using . This creates a "Harvest Now, Decrypt Later" threat, where adversaries steal encrypted data today to unlock it once quantum technology matures. 1. Post-Quantum Cryptography (PQC) Decrypt Later" threat
