Cryptographic Operations are run Before Supporting Units are Ready

Cryptographic hardware often relies on other system components to function securely. For example, an encryption module might need a true random number generator for entropy or require keys from a secure storage unit. If crypto operations begin before these supporting units are fully operational—like reading keys from an uninitialized fuse bank or using predictable values from a not-yet-ready RNG—the cryptographic output becomes weak or predictable, undermining the entire security mechanism. Developers must implement explicit readiness checks and proper initialization sequences before invoking any cryptographic functions. This means verifying that entropy sources are producing true randomness, key storage is accessible, and all hardware dependencies are in a secure state. Failing to enforce this dependency chain creates a race condition where crypto operations execute with invalid or default inputs, leading to easily breakable encryption, weak keys, or other cryptographic failures that attackers can exploit.
