Question

Which of the following statements is/are true (For cryptography) ?

1.0 SET and IPSec are cryptography protocols.

2. Receiver decrypts the message using their private key.

3. Sender gets receiver's public key from databse.

4.

All of the above.
​

Answer 1

The correct statement is - Receiver decrypts the message using their private key.

• Only IPSec is a series of services and security protocols based on cryptography securing communication between devices that move traffic via an untrusted network.

• A single key is shared for private key encryption devices. To encrypt the direct note, the sender employs the private key and the receiver decrypts it with the comparable one. Both must keep the key private for a confidential communication.

• Via some secure source, sender receives the public key. The recipient sends the public key on same channel as one the message is intended to receive, but a trusted external party to verify key's validity.

Answer 2

Explanation:

Among the various options given in question statement the correct option is the second one.

In cryptography, the receiver decrypts the message using their private key

In asymmetric cryptography, there are two keys, one is a public key while the other is a private key. This private key is the secret key and it will used to protect the communication between users
