IPSec Architecture Essay Example for Free

IPSec Architecture Essay IPSec is a collection of protocols tied together to apply it’s potential as specified in the IPSec Architecture. It is necessary to comprehend the relationships and interaction of these protocols. Along with the design of the IPSec Architecture, various security documents like ESP ( Encapsulating Security Protocol) , AH (Authentication Header) and Antireply protection defines the protocol, the payload header format, and the services they provide. IPSec works by enabling a system to select its own security protocol, algorithms and cryptographic keys as required by the services. Versatile, it can protect multiple â€Å"paths† between hosts, security gateways or between host and security gateway. Security services provided by IPSec at the IP Layer are access control, connectionless integrity, data origin, and authentication, rejection of replayed packets, encryption, and limited traffic flow confidentiality. While services are provided in the IP layer, protocols like TCP, UDP, ICMP, BGP, and other IP based protocols can take advantage of IPSec. The better understand the relationship of between Protocols and Algorithms in the IPsec Architecture: The standard algorithm is placed to initiate interoperability in the Internet and combine with IPSec Traffic Protection and Key Management protocols allow systems and application developers to install superior, internet layer, cryptographic security technology.
