IPSec / IP Security

  • IP Security, also known as IPSec is the protocol that allows the encryption of layer 3 communications with point to point connections. IP sec uses a number of sub protocols:
  • Encapsulated Security Payload (ESP): encrypts content with symmetrical algorithm
  • Authentication Header (AH): creates checks sum and hashes a data packet
  • IP Comp/IP Payload Compression: compresses IP payload
  • Internet Key Exchange (IKE): negotiates shared secret. In transport mode, it encrypts data while in tunnel mode it encrypts packets.

Internet Security Association on Key Management Protocol (ISAKMP): This is the procedure that works with IPSec Communications. It exchanges keys and provides security association and then creates the tunnel.
