Types of Encryption
IPSec defines two types of encryption algorithms. One type, symmetric encryption, encrypts our bulk data. The other type of algorithm, asymmetric, encrypts very small amounts of data.
 | Encryption deters man-in-the-middle attacks. |
Symmetric and Asymmetric Encryption
The end result required of IPSec is confidentiality, which is provided by encrypting data. It is the easiest part of IPSec to accomplish. To encrypt data, the plaintext data is broken into pieces and inserted along with an encryption key into the encryption algorithm. The output of the algorithm is ciphertext and is sent to the peer. The peer performs the same algorithm ...
