Question
Encapsulating Security Payload (ESP) provides what kind of service correct answer?
Solution
Encapsulating Security Payload (ESP) provides confidentiality, data integrity and authentication services.
Here's a step-by-step explanation:
-
Confidentiality: ESP encrypts the data being sent, ensuring that only the intended recipient can read it. This is done using symmetric key cryptography where the same key is used to encrypt and decrypt the message.
-
Data Integrity: ESP ensures that the data has not been tampered with during transmission. It does this by creating a hash of the data and then sending this hash along with the data. The recipient then creates a hash of the received data and compares it with the received hash. If they match, the data has not been tampered with.
-
Authentication: ESP verifies the identity of the sender to prevent impersonation attacks. This is done using a pre-shared secret key. The sender uses this key to create a digital signature which is then sent along with the data. The recipient uses the same key to verify the signature and thus, the identity of the sender.
