Correct option is B
Encryption is the process of converting plain text into a coded format, called
cipher text, which is unreadable without a decryption key. This ensures data security and prevents unauthorized access.
Important Key Points:
1.
Encryption: Protects sensitive data by encoding it, commonly used in secure communications and storage.
2.
Cipher Text: The result of encryption, which requires a decryption key to revert to readable form.
3. Widely used in banking, online transactions, and secure messaging applications.
Knowledge Booster:
·
Breaching: Refers to unauthorized access or exploitation of a system, unrelated to encryption.
·
Decryption: The reverse process of encryption, converting cipher text back to plain text.
· Common Encryption Algorithms:
AES (Advanced Encryption Standard),
RSA, and
DES.
