MEDINA V2: The Real Threats

"Unbreakable" designs don't fail because of brute force — they fail because of human mistakes. V2 addresses every implementation-level vulnerability that matters in real-world cryptography.

Weak Randomness

If the random number generator isn't truly 256-bit entropy, the entire security model collapses. V2 validates entropy sources, rejects insufficient randomness, and supports hardware RNG.

In Progress

Key Reuse / Leakage

Reusing a key with different data leaks information. V2 enforces single-use keys, tracks key usage, and warns on reuse attempts.

In Progress

Side-Channel Attacks

Timing attacks, power analysis, cache-based attacks can extract keys without breaking the math. V2 implements constant-time comparisons and operations throughout.

In Progress

AES Mode / IV Safety

IV reuse in CBC mode is catastrophic. V2 guarantees unique IVs per operation, validates IV length, and adds integrity checking.

In Progress

Key Storage

Keys in memory, swap files, or core dumps are recoverable. V2 implements secure memory erasure, mlock'd buffers, and key derivation-on-demand.

In Progress

Code Bugs

Buffer overflows, integer overflows, off-by-one errors. V2 adds comprehensive input validation, size checks, and fuzzing-ready test harness.
