IPv6 implements security at the Internet layer with an encrypted security payload (ESP) extension
header. What is this security concept called?

A.
Authentication.

B.
Initialization.

C.
Padding.

D.
Confidentiality.

Explanation:
The ESP is used for encryption services. When the packet is encrypted, only those who have the
correct keys can decrypt the data and read it. If you don’t have the keys, you can’t read the data.
The data is protected from unauthorized entities from reading the data, so the data’s confidentiality
if maintained.
Incorrect Answers:
A: Authentication of the packet is accomplished by the authentication extension header, which
would be designated by the Next Header Field by a code 51.
B: This is not termed initialization.
C: This is not termed padding.
