A new dynamic multilayer IPSec protocol

Abstract

Performance Enhancing Proxies (PEPs) are used in satellite networks for better performance of the TCP/IP applications. Multi-layer IPSec (ML-IPSec) resolves the conflict between end-to-end security in standard IPSec and operation of PEPs. Previous Ml-IPSec solution has issues of limited application scope and increased complexity to implement and process the ML-IPSec protected data. This paper presents a new dynamic ML-IPSec protocol which addresses these issues. The paper also analyzes the protocol with reference to previous ML-IPSec protocol and presents the experiment performed to analyze the network performance while running IPSec and ML-IPSec.
