Consider the following statements regarding the encryption: It protect...
End-to-end (E2E) encryption protects information in a way that has transformed human rights organisations’, law-enforcement agencies’, and technology companies’ outlook on their ability to access and use information.
- Encryption is a way of protecting data from unauthorised access or tampering.
- It works by transforming the data into a secret code that only the intended recipient can decipher.
- This comes in useful for various cases, such as securing online communications, storing sensitive information, and verifying digital identities.
- There are two main types of encryption:
- Symmetric: It uses the same key to encrypt and decrypt the data. In symmetric encryption, the key used to encrypt some information is also the key required to decrypt it.
- Asymmetric: It uses a pair of keys: one public and one private. The public key can be shared with anyone, but the private key must be kept secret.
- The term encryption is generally used when referring to the privacy of stored data, while end-to-end encryption protects data as it’s transferred between a location – which is crucial wherever there’s a rapid exchange of information.
- In an E2EE-enabled app, only person on each end – the sender and receiver – can read any exchanged messages.
- This is because messages get encrypted on your device before being sent and only are decrypted when they reach your intended recipient.
Hence only statement 1 is correct.

Consider the following statements regarding the encryption: It protect...
Explanation:
Statement 1: It protects data from unauthorised access.
- This statement is correct. Encryption is a method used to secure data by converting it into a code that can only be accessed or understood by people who have the correct decryption key. This process ensures that even if unauthorized individuals gain access to the encrypted data, they will not be able to decipher it without the key.
Statement 2: Symmetric encryption uses the different key to encrypt and decrypt the data.
- This statement is incorrect. In symmetric encryption, the same key is used for both encryption and decryption. This means that the sender and receiver must both have access to the same key in order to communicate securely. Asymmetric encryption, on the other hand, uses different keys for encryption and decryption.
Therefore, the correct answer is option 'A' - 1 only.
