In the above figure: SPIs (Security Parameter Indexes) are connection unique identifiers chosen by the endpoint (initiator and responder) themselves. Incoming IKE packets are mapped to an IKE SA only using the packet's SPI. Multiple sessions per peer are possible.

WebESP Header: This contains two fields, the SPI and Sequence Number, and comes before the encrypted data. Its placement depends on whether ESP is used in transport mode or tunnel mode, as explained in the topic on IPSec modes. ESP Trailer: This section is placed after the encrypted data. WebA standard GRE packet header structure [7] is represented in the diagram below. C (1 bit) Checksum bit. Set to 1 if a checksum is present. Reserved 0 (12 bits) Reserved bits; set to 0.

WebDec 12, 2024 · ESP or Encapsulation security payload is an individual protocol in IPSec. ESP is responsible for the CIA triad of security (Confidentiality, Integrity, Availability), which is considered significant only when encryption is carried along with them. Securing all payload/ packets/ content in IPv4 and IPv6 is the responsibility of ESP. Authentication Header (AH) is a member of the IPsec protocol suite. AH ensures connectionless integrity by using a hash function and a secret shared key in the AH algorithm. AH also guarantees the data origin by authenticating IP packets.
