In a cybersecurity context, what is the main goal of encryption?

• A. To ensure speed of data transmission
• B. To make data unreadable without a key
• C. To simplify data analysis
• D. To reduce data volume

Answer: (B)

The main goal of encryption in a cybersecurity context is to make data unreadable without a key. This process transforms plaintext into ciphertext using cryptographic algorithms, ensuring that only individuals with the appropriate keys can decrypt and access the original data. Encryption serves as a critical safeguard for sensitive information, protecting it from unauthorized access and ensuring confidentiality. In this way, even if encrypted data is intercepted during transmission or accessed by an unauthorized user, it remains unintelligible without the corresponding decryption key, thereby maintaining the integrity and privacy of the data. This characteristic makes encryption an essential component in securing communications, protecting personal information, and complying with various data protection regulations.
