Certified Cloud Security Professional (CCSP) Practice Exam 2024 - Free CCSP Practice Questions and Study Guide.

The correct answer is Encryption Key because encryption keys are essential for both encrypting and decrypting messages in encryption software. When data is encrypted, an encryption key is used to transform the data into ciphertext, making it unreadable without the corresponding decryption key. The decryption key, which is usually related to the encryption key, is needed to revert the ciphertext back to its original plaintext form. Encryption keys play a critical role in securing data and ensuring confidentiality in communication. Crypto-shredding is a method used to securely erase data by overwriting it several times to prevent data recovery. Digital Rights Management (DRM) is a technology used to protect digital content and control its distribution. Homomorphic Encryption is a type of encryption that allows computations to be performed on encrypted data without decrypting it first.
