Beyond Encryption: The Expanding Frontier of Post-Quantum Cryptography
Public-key cryptography, developed in the mid-1970s, established the foundations on which the modern internet was built.

Modern digital systems increasingly require capabilities that reach beyond encryption and authentication , the ability to prove properties without revealing them, to authenticate anonymously while still detecting duplication, to prove possession of a secret key without exposing it.
It provides a brief overview of the standards baseline, articulates the class of capabilities that extend beyond it, and examines three recent research contributions from the center , in certificate infrastructure for post-quantum key exchange, anonymous authentication with programmable linkability, and ring signatures that preserve anonymity while catching duplicate signers , as illustrations of what frontier work looks like today.
