Integration of Robust Header Compression over IPsec Security Associations

Design Aspects of a Testbed for an IPv6-Based Future Network for Aeronautical Safety and Non-Safety Communication

“…Note: compression gains, respectively, implementation complexity is significantly affected by IPsec deployment, in particular if encryption is used (cf. next bullet)  if IPsec is deployed the relatively new RoHCoIPsec related RFCs could be implemented (Ertekin et al, 2010a(Ertekin et al, , 2010b(Ertekin et al, , 2010c and deployed in the respective IPsec gateways,  between the IR and the AR, e.g. within a point-to-point protocol (PPP) context, if supported by the AR.…”

“…4. A framework for integrating RoHC over IPsec (RoHCoIPsec) is defined in (Ertekin et al, 2010a). It defines the modification required in IPsec protocol stack to allow the compression of IPsec encrypted packets.…”

A cross‐layer framework for IPsec over satellite links

“…IPsec introduces overhead that reduces the bandwidth efficiency [34,35]. Such overhead not only impacts wireless link efficiency, but can also increase the probability of corruption due to errors from the increased header.…”

“…Such overhead not only impacts wireless link efficiency, but can also increase the probability of corruption due to errors from the increased header. Header compression at the IPsec endpoints can mitigate this drawback when used on the payload of the IPsec packet (header compression over IPsec, HCoIPsec [34]). The HCoIPsec framework employs existing header compression between the IPsec SA endpoints.…”

“…The outbound IP traffic is first compressed and then encrypted/ authenticated. An inbound IP traffic is first decrypted/authenticated and then decompressed [34]. Figure 6 shows an example for AH in tunnel mode.…”
