Question

True/False A virtual private network is a way to use the Internet to create a connection between a remote user and a central location. IPsec encrypts the packet data but not the header information. L2TP uses IPsec for its encryption. Kerberos is an authentication protocol used for logging into Windows and uses a ticket granting system that sends an encrypted ticket to the user's machine. A digital signature is used to guarantee who sent a message. This is referred to as authenticity. Public key encryption is fast becoming the most widely used type of encryption because there are no issues to deal with concerning distribution of keys. PGP involves private key encryption. The most widely used symmetric key algorithm is Advanced Encryption Standard. Cipher text is encrypted text. Binary numbers are made up of 0s and 1s.

Explanation / Answer

Answer:

1) True

explanation:

=> A VPN, or Virtual Private Network, allows you to create a secure connection to another network over the Internet.

2)true

explanation:

=>IPsec includes Encapsulating Security Payload (ESP) to encrypt the data and provide confidentiality

3) TRUE

explanation:

=> L2TP does not encrypt the tunnel itself but often uses IPsec for encryption.

5) True

explanation:

=> Digital signatures are the public-key primitives of message authentication.

=> A valid digital signature gives a recipient reason to believe that the message was created by a known sender.

6) True

explanation:

=> Public key encryption in turn provides a solution to key distribution and data transmission issues. Used together, performance and key distribution are improved without any sacrifice in security.

7) False.

8) True

explanation:

=> Encryption algorithms that use the same key for encrypting and for decrypting information are called symmetric- key algorithms.

=>The symmetric key is also called a secret key because it is kept as a shared secret between the sender and receiver of information.

9) true

explanation:

=>An encryption function takes cleartext and a key as input and returns ciphertext.

10) TRUE

explanation:

=>A binary code represents text or computer processor instructions using the binary number system's two binary digits, 0 and 1.
