Показать описание
This lecture describes the ESP protocol of IP Security. This is the third lecture of IP Security. I strongly recommend that the viewer should watch it in a sequential manner.
Link to the other two videos are as follows:

The series of lectures will cover the following. So keep watching.
Two modes of IPSec:
1. Transport Mode
2. Tunnel Mode
Two versions of Protocol
1. AH (Authentication Header)
2. ESP (Encapsulating Security Payload)
Then we talk about the Security Association: A technique that changes the connectionless service of the network layer to a connection-oriented service for the purpose of applying security measures.
Finally, one application of IPSec: VPN (Virtual Private Network)
