Hidden AI capabilities can be made cryptographically undetectable, NeurIPS paper proves
AI safety evaluation faces a new mathematical limit: a NeurIPS 2026 paper proves that anyone with access to model weights can embed a hidden neural network protected by SHA-3 cryptography that no ...
Voltar a escrever sobre hash functions é, para mim, uma volta às origens. Durante minha trajetória como professor universitário, lecionei disciplinas de Redes de Computadores e Segurança da Informação ...
Hash functions turn data of any length into fixed-size values. Software uses them for hash tables, caches, deduplication, file checks and database indexes. A collision sends two different inputs to ...
Ethereum Foundation abandons the Poseidon hash for L1, switching to SHA-2 or BLAKE. Binary-field proof systems let standard hash functions match Poseidon speeds. A production leanVM is penciled in for ...
bcrypt remains the most widely deployed password hashing function in the Node.js ecosystem, and in 2026 it still earns its place. The OWASP Password Storage Cheat Sheet lists Argon2id as the first ...
vectorize text documents that are preprocessed (tokenized) with the help of a custom Python function. Later we introduce and analyze the text-specific vectorizers ...
Cryptographic hash functions are the foundation of modern blockchain systems and cybersecurity. They play a crucial role in ensuring data integrity, enabling digital signatures, and verifying ...
