IPec can be used 10 protect network data, for example, by setting up circuits using IPsec (请作答此空), in which all data being sent between two endpoints is encrypted, as with a Virtual ( ) Network connection ;for encrypting application layer data ;and for providing security for routers sending routing data across the public internet. Internet traffic can also be secured from host to host without the use of IPsec, for example by encryption at the ( ) layer with HTTP Secure (TTPS)or an the transport layer wit the Transport Layer Security (TLS)protocol.
