Why is the concept of split knowledge important in nuclear operations?

The concept of split knowledge is crucial in nuclear operations primarily because it prevents unauthorized access to sensitive information. This practice ensures that no single individual has complete knowledge of the entire nuclear system or the necessary codes, controls, and procedures required to access nuclear weapons or materials. By requiring multiple individuals to have a portion of the knowledge—such that they must work collaboratively to gain access—this safeguards against internal and external threats, minimizing the risk of nuclear proliferation and misuse.

The rationale is that unauthorized access could lead to catastrophic consequences, so split knowledge acts as a security measure that adds layers of protection. It promotes accountability and necessitates checks and balances, ultimately contributing to the overall security framework in nuclear operations.
