IPsec
IPsec (IP security) is a standard for securing Internet Protocol (IP) communications by encrypting and/or authenticating all IP packets. IPsec provides security at the network layer. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

~ ~ ~ ~ ~ ~ ~ ~ ~ ~ IPsec is a set of cryptographic protocols for (1) securing packet flows and (2) key exchange. Of the former, there are two: Encapsulating Security Payload (ESP) provides authentication, data confidentiality and message integrity; Authentication Header (AH) provides authentication and message integrity, but does not offer confidentiality. Originally AH was only used for integrity and ESP was used only for encryption; authentication functionality was added subsequently to ESP. Currently only one key exchange protocol is defined, the IKE (Internet Key Exchange) protocol. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
