Network CryptoGate: a new mobile security solution

摘要

Network CryptoGate (NCG) is the first product in the world to successfully combine both mobility and security. NCG adheres to the mobile-IP and IP-security standards of the Internet Engineering Task Force (IETF). Using mobile-IP technology, NCGprovides complete accessibility for a mobile terminal as if it was directly connected to its original network when connected to a foreign network. NCG uses IETF standard P-security technology to encrypt and authenticate data packets, constructing secureconnections through the Internet. Because these features are supported at the IP layer, upper-level applications work without requiring either changes or special setups.
