ECCouncil CCISO 712-50 Question # 64 Topic 7 Discussion

Split knowledge ensures that no single individual can independently generate or reconstruct an encryption key. This principle divides knowledge of the key among multiple individuals, requiring their collaboration for key generation or usage. While dual control involves multiple individuals acting together, split knowledge specifically ensures that individual actions alone cannot compromise key integrity. Separation of duties and least privilege focus on broader security principles rather than encryption-specific safeguards.
