Encryption | MCQs

Explanation

Explanation

Encryption is the process of converting plaintext data into a coded, unreadable form to protect it from unauthorized access.

The primary purpose of encryption is to ensure the confidentiality and security of sensitive information.

Explanation

A digital signature verifies the authenticity of an email by confirming the sender's identity and ensuring the message hasn't been altered.

It uses cryptography to validate the sender's identity and ensure the integrity of the email content.

Explanation

By encryption of a text, we mean scrambling it to preserve its security

Explanation

• HTTPS (Hypertext Transfer Protocol Secure) is an extension of the Hypertext Transfer Protocol (HTTP) used for secure communication over the internet.
• It combines HTTP with an additional security layer, typically Secure Sockets Layer (SSL) or Transport Layer Security (TLS), to encrypt and protect the data being transmitted between a website and a user's browser.

Explanation

In cryptography, the one-time pad is an encryption technique that cannot be cracked, but requires the use of a single-use pre-shared key that is not smaller than the message being sent. In this technique, a plaintext is paired with a random secret key.

Explanation

Hypertext Transfer Protocol Secure is an extension of the Hypertext Transfer Protocol.

It is used for secure communication over a computer network, and is widely used on the Internet.

In HTTPS, the communication protocol is encrypted using Transport Layer Security or, formerly, Secure Sockets Layer. 

Explanation

Key function of firewall: Monitoring

Mechanism to protect network from outside attack is: firewall

Explanation

In cryptography, encryption is the process of encoding information.

This process converts the original representation of the information, known as plain text, into an alternative form known as cipher text.
