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 . 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. Nature 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 is based on lattice math. NIST's PQC contest Lattice crypto is often based on the . A problem where, given a basis of a and a , the goal is to find the shortest non-zero vector. shortest vector problem vector space norm In addition, Matthew Dozer has a great introductory video: Lattice-Based Crypto for IOT (Khalid, McCarthy, O'Neill) Lattice Based Cryptography - Wikipedia Bitcoin - Schnorr Signatures Instead of the current implementation, Bitcoin might be switching to in order 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. ECDSA Schnorr signatures More Rigorous Testing of Hash Functions Also, Nicky Mouha 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 published a paper https://www.nist.gov/publications/extending-nists-cavp-testing-cryptographic-hash-function-implementations Thanks Lane on Twitter: @wagslane Lane on Dev.to: wagslane Download Qvault: https://qvault.io Star our Github: https://github.com/q-vault/qvault
