How to Store Sensitive Info in 2020?
Reviews best practices and modern architectural patterns for encrypting and securely storing sensitive data in cloud environments.
Summary
In this cryptographic architecture tutorial from the DEF CON Safe Mode Crypto Village, a security researcher delivers an authoritative guide on modern cryptographic algorithms for protecting sensitive data and credentials at rest. Opening at 00:02, the presenter highlights why legacy hashing algorithms are no longer sufficient to protect sensitive secrets against modern offline attack hardware.
At 11:00, the session examines key derivation functions (KDFs), detailing the internal design of memory-hard functions that force attackers to expend extensive hardware resources during brute-force attempts. At 22:01, the speaker provides an in-depth breakdown of Argon2, contrasting the side-channel resistance of Argon2i with the GPU cracking resistance of Argon2d.
At 33:00, the presentation reviews the processing capabilities of modern GPU password-cracking rigs, concluding at 44:00 with practical implementation guidance on tuning memory size, iteration counts, and thread parallelism to secure enterprise password storage. (AI summary — Gemini Flash)
