Cryptography Trends And News Going Into 2020

By Lane Wagner on Jan 3, 2020

Quantum Computing

Quantum computing may not be coming quite as fast as some in the field had certainly feared (or perhaps hoped). Google did, however, solve an impressive problem this year.

They published a paper in Nature. It stated that their quantum processor solved a problem that, in contrast, a digital computer would take 10,000 years to solve. The problem that was solved deals with generating certifiably random numbers. Their processor, ‘Sycamore’, uses 53 qubits, which corresponds to a search space of 1016.

Regards and sorry for the interruption, Lane here! I built to give you a place to learn back-end development the...hard way? I mean easy? Maybe the "heasy" way? I don't know.

It's hard because you will have to write code... like a metric ton of code. It's easy because my courses have a built-in game that's pretty darn fun. Give it a try.

Lattice-Based Cryptography

Lattice-based Cryptography (LBC) is one of our best bets for secure “Post Quantum Cryptography”. Therefore, almost half of the second round of NIST’s PQC contest is based on lattice math.

Lattice crypto is often based on the shortest vector problem. A problem where, given a basis of a vector space and a norm, the goal is to find the shortest non-zero vector.

In addition, Matthew Dozer has a great introductory video:

Bitcoin - Schnorr Signatures

Instead of the current ECDSA implementation, Bitcoin might be switching to Schnorr signatures to get more efficiency when signing transactions. Instead of signing each transaction separately, with Schnorr, we can generate a single signature to validate many transactions at once. This allows Bitcoin to scale by requiring less data to be broadcast on the network when grouping transactions.

Want to learn Python and Go?

The rumors are not true. I've been writing Go and Python for many years and I smell delightful.

More Rigorous Testing of Hash Functions

Also, Nicky Mouha published a paper exposing a vulnerability in Apple’s CoreCrypto Library. This affects 11 out of 12 implemented hashes. However, MD2 is the only function to remain secure. As a result, a new test is founded which can help detect similar problems moving forward.
