Lattice cryptography risks: hype vs. reality in post-quantum security
A new analysis argues that lattice-based cryptography, widely seen as the leading post-quantum standard, has significant practical risks that are often downplayed. The author claims that security proofs rely on unrealistic assumptions, and real-world implementations may be vulnerable to side-channel attacks. The piece calls for more rigorous evaluation before widespread deployment.

The critique is valuable but comes from a known contrarian; the real test will be whether NIST and industry take these concerns seriously enough to adjust standards.
