Криптографічний захист відеопотока для системи Ruby FPV

Cryptographic video stream protection for unmanned aerial vehicles based on the Ruby FPV system. Implements a RAM-only key storage architecture with a Shamir Secret Sharing Scheme (2-z-2) to protect against physical capture of the device.Includes: ChaCha20-Poly1305 and AES-256-GCM encryption with automatic selection based on hardware capabilities; ECDH key exchange protocol on Curve25519 elliptic curve with Ed25519 authentication; HKDF-SHA256 key output function according to RFC 5869; heartbeat monitoring with automatic key wipe; cryptosystem state machine. Provides video stream protection with a delay of less than 25 microseconds per packet.
